What an inspired substitution by Louis van Gaal, with late substitute Tim Krul saving 2 of Costa Rica's 5 penalties to send the Netherlands through to the semi-finals. Thanks for joining me in another sensational World Cup 2014 game.
TIM KRUL SAVES THE PENALTY! THE NETHERLANDS ARE THROUGH TO THE SEMI-FINALS!
DIRK KUYT MAKES IT 4-3! Costa Rica have to score!!
COSTA RICA'S BOLANOS MAKES IT 3-3!
WESLEY SNEIJDER SCORES FOR NETHERLANDS! It's now 3-2.
COSTA RICA'S GONZALEZ MAKES IT 2-2! Fires it into the top right corner!
ARJEN ROBBEN SCORES! Fires it into the top right corner to make it 2-1!

ROBIN VAN PERSIE SCORES! Drives his penalty into the bottom left corner beyond Navas. 1-1!
First up it's Celso Borges for Costa Rica. HE SCORES! 1-0 TO COSTA RICA!
What a sensational end to the game that was. Stick with us for our live commentary of the penalty shootout!
We're going to penalties!
Incredible substitution as Tim Krul comes on for Jasper Cillessen.
Robben breaks and finds Kuyt on the edge of the area, whose shot is deflected away from danger.
SNEIJDER HITS THE BAR! The playmaker picks up from 20 yards, cuts inside and whips a sumptuous effort over Navas but not under the bar. It cracks off the underside of the woodwork and Costa Rica get away with it.
It's now Netherlands' turn to attack and after sustained pressure from Robben and Lens, Costa Rica manage to hold on again. Resilient defending!
Urena skips past a couple of challenges and is one-on-one with Cillessen, but the Ajax man gets down well to save. What a moment that would have been! Incredible end to the game.
That first corner, though, is a poor one. It's over-hit by Bolanos and it flies straight out for a goal-kick.
It's Costa Rica who are coming on the more strongly now! Bolanos fires in on goal, but his shot is deflected behind for their first corner of the entire match.
Great play from Bolanos as he weaves in and out of the Dutch defence, but Vlaar puts in a last-ditch tackle to block his shot. Would have been a historical goal!
Play resumes as Tim Krul warms up on the touchline. Could he be set for a late substitution?
Huntelaar booked after catching Navas' face with his arm.
Van Persie tries to thread the ball through to Huntelaar, but after a lack of understanding the Man United man over-hits his ball and it goes through to Navas.
Netherlands get a corner, and Robben delivers it onto the head of Huntelaar who heads it harmlessly over the bar - giving Navas and Costa Rica a bit of a breather.
After a bit of a scramble in the area, Costa Rica unsurprisingly clear away as the Dutch continue to turn the screw.
Robben sprints past Acosta and collides with the Costa Rican defender, which gives the Netherlands a free-kick ten yards inside from the right-hand corner spot. Chance for Robben to deliver a dangerous ball into the area.
The second half is underway!
Klaas-Jan Huntelaar comes on for Martins Indi (Netherlands)
End of the first period of extra time. 15 minutes left!
Two minutes of added time to be played.
Ruiz tries to thread the ball through to Urena, who had peeled away from Vlaar, but his pass is uncharacteristically over-hit and the it dribbles through to Cillessen.
The resulting free-kick hits the wall and Costa Rica clear the ball away from danger.
Superb piece of wingplay from Robben as he bursts on the wing, cuts inside and shoots on goal, but Diaz blocks the shot well. It comes back out to Robben, who tries another shot but it hits the arm of Diaz and the Dutch get a free-kick 25 yards from goal...
Ruiz goes down after a late Martins Indi challenge, and the ball is angrily kicked out of play by Sneijder. Ruiz is looking for a second yellow for Martins Indi, but he won't get his wish.
Tiredness, understandably, creeping into both sides' play. Vlaar plays a wildly over-hit ball over the Costa Rican defence which goes out for a goal kick.
Urena goes down in the area under a a Vlaar challenge, but the referee waves away an appeals. Replays show that it would have been soft, but they have been given in the past.
Yeltsin Tejeda comes off for Jose Cubero
After a brief delay, Sneijder whips in another corner but it's cleared away from danger.
CHANCE! Robben's delivery finds an unmarked Vlaar, but his header is palmed away by Navas and out for a corner. Navas then tries to punch away the resulting corner, and completely misses it. He's now in a heap on the ground, in some considerable pain.
Persistent play on the right-hand side from Kuyt forces Costa Rica to concede a corner, which Robben will take...
De Vrij pays a long ball over the top towards on an onrushing Robben, but for the tenth time tonight, the Netherlands are flagged for offside.
Netherlands get extra-time underway!
Somehow, Costa Rica have held on and the game will go into extra time!
How has it not gone in?! Blind plays the ball across the area, which misses three Dutch players who are five yards out, and it comes to van Persie on the edge of the area, whose effort is cleared off the line by Tejeda! It also hits the bar, and it's then eventually cleared away from danger.
Van Persie's freekick is palmed away by Navas, but the Dutch continue to knock on the door.
Robben is brought down on the edge of the area after a mistimed tackle from Diaz, who has already been cautioned, but the referee avoids sending him off. Big opportunity for the Dutch here.
Four minutes of stoppage time to be played.
One minute left of added time as Costa Rica stick ten men behind the ball in a desperate attempt to secure extra time.
CHANCE! Sneijder delivers a wonderful ball towards van Persie, three yards out, who completely misses the ball! The ball slips under his foot and goes out for a goal-kick. Incredible miss.
Lens tries to take it past Gonzalez as he approaches the area, but the Costa Rican defender executes a perfectly timed sliding tackle to clear the danger for now, and boost his chances of a man-of-the-match award.
Set for a grandstand finish as Netherlands look to get the result sorted without the need for extra time.
Van Persie colects a long ball from de Vrij on the edge of the area, but he can't get it out of his feet just when it looked like he was one-on-one with Navas. Gonzalez gets back to clear.
Robben is fouled again on the right byline and his free-kick causes a bit of a scramble in the area, with the ball falling to van Persie who drives it into the legs of Navas. The ball is eventually cleared, as Costa Rica look to survive this onslaught.
SNEIJDER HITS THE POST! The midfielder whips a wonderful free-kick over the wall to leave Navas sprawling, as the ball crashes off the post and away out of danger. So close!
Giancarlo Gonzalez booked for the foul on Robben.
Robben skips past Gonzalez on the edge of the area and is brought down by the Costa Rican defender, and the referee awards a free-kick. Tantalisingly close to being a penalty.
Kuyt curls a sumptuous ball into the path of Lens, free in the area, whose header is palmed away by Navas. Wouldn't have counted though, as Lens was offside.
Cristian Gamboa comes off on a stretcher for Dave Myrie (Costa Rica)
Robben skips past Diaz and tries to cut it back to Kuyt in the area, but it's well defended and the ball deflects out for a corner.
Memphis Depay comes off for Jeremain Lens (Netherlands)
Great delivery from Sneijder finds an unmarked Vlaar, but he scoops his header over the bar and it goes out for a goal kick.
Gamboa concedes a free-kick deep inside the Costa Rican half after putting his foot high into a challenge with Daley Blind. Sneijder stands over the ball by the left byline.
Gamboa returns to the pitch with what seemed like a temporarily jarred knee. Seems fine to carry on.
After a brief pause in play, the game resumes with Cillessen in possession
Gamboa goes up for a header on the right byline over the half-way line, lands awkwardly and immediately calls for the physio. Doesn't look good for the Costa Rican.
Robben sprints towards goal and fires the ball into van Persie in the area, who touches it off for Robben, but Tejeda had tracked his man and manages to get to the ball first and clear. The resulting corner is defended well.
Urena finds Gamboa on the right, who has time to deliver it into the area, but his cross is over-hit and it evades the head of Borges and goes out for a Dutch throw-in.
Joel Campbell comes off for Marcos Urena (Costa Rica)
Bolanos' delivery lands on the head of Gonzalez six yards out, but Vlaar manages to nudge the Costa Rican which forces him to head high over the bar.
Another Bolanos ball to come, with the midfielder standing over the ball from 40 yards out.
Bruno Martins Indi is booked after pulling down Brian Ruiz.
De Vrij's challenge showed signs of frustration creeping into the Netherlands' play, who are struggling to breakdown a resilient Costa Rica.
Bolanos signals that he's delivering a ball into the area, but instead takes a shot on goal in an attempt to catch CIllessen out. Unfortunately for Bolanos, it flies too high and wide.
Campbell picks the ball up 35 yards from goal, and is bundled to the ground by a strong challenge from de Vrij. Good opportunity for Pinto's side.
Costa Rica break on the counter through Diaz, who cuts the ball back towards Campbell in the area, who goes down under the challenge from Martins Indi. The referee rules it's not a penalty, and play continues.
Robben gets another chance to deliver a dangerous corner into the Costa Rican area, but they managed to clear the ball once again.
Great control on the right-hand side from Robben to keep the ball in, and he arrows a ball towards Kuyt, in the area, who is ushered away from goal by Gonzalez and eventually the ball is cleared.
Just over ten minutes gone in the second-half, and neither team have managed to carve out a good opportunity as of yet...
Robben delivers a corner into the heart of Navas' box, but once again it's cleared comfortably by the Costa Rican defence, who have looked unflappable so far.
Costa Rica continue to keep ten men behind the ball. Will be interesting to see whether they will change their approach and start to attack the Dutch backline.
Robben drills it towards Sneijder, on the edge of the area, who scoops his effort harmlessly over Navas' bar and out for a free-kick. An imaginative free-kick that lacked a clinical finish.
Michael Umana cautioned for his foul on Robben
Robben gets the ball on the right-hand side, cuts inside and is fouled on the corner of the Costa Rica area. Dangerous free-kick for Holland here as Robben steps over it.
The ball is aimed towards van Persie who tries to flick a header into the path of the onrushing Robben, who had burst into the area, but van Persie mistimed his header and Navas clears.
Early signs show that Costa Rica's rigidity remains, as they continue to look impressively organised.
Cagey, quiet start in Salvador as both sides attempt to control possession.
Depay tries to weave past three players on the edge of Costa Rica's area, but Umana eventually takes the ball off the PSV striker before he can have an attempt on goal.
Bolanos picks up the ball on the left-hand side, tries to shimmy it past de Vrij but the defender stays strong and ushers the ball out for a Costa Rican throw deep inside the Dutch half.
Netherlands get the second-half underway!
Half time in Salvador, and it remains 0-0. The Netherlands have had the best chances of the half, but Navas has remained firm in the Costa Rican goal. Costa Rica look superbly disciplined, and it looks like a moment of magic will be required from van Gaal's side.
One minute of added time has been announced
Costa Rica keep the ball in midfield, but Tejeda's guilty of over-excitement as he plays a long-ball through to no-one, and the ball trickles out for a goal-kick.
Depay plays a reverse pass into van Persie but Umana stands strong in the area and forces RVP into the foul, giving his side time to regroup at the free-kick.
Robben slips through van Persie who's free in the area, but Navas sprints off his line expertly to smother the ball. Superb goalkeeping.
Costa Rica have ten behind the ball and the Dutch are forced to play the ball back towards the defence. Good discipline from Pinto's side, who look content to keep the scores level at the break.
The resulting corner is cleared into the path of Depay, who rather comically completely misses the ball on the volley and swipes through thin-air, giving Costa Rica the chance to clear.
GOOD SAVE! Sneijder curls a great effort to the left-hand side of the goal, but Navas is agile enough to palm away the Dutchman's effort behind for a corner.
Junior Diaz is booked for the foul on Robben.
Wijnaldum attempts a dinked pass over the defence into the path of Robben, who's tripped by Diaz 30 yards from goal. Free-kick for the Netherlands in range of the goal.
Robben's delivery from the resulting free-kick is very poor, and it fails to beat the first man who clears it away towards the Dutch backline.
Bolanos finds Gonzalez at the back post, who heads it down towards Ruiz who tries an acrobatic bicycle kick but it's a tame effort and the Netherlands clear, and on the counter Robben is felled midway inside the Costa Rican half.
Wijnaldum trips up Borges, a little further than the last free-kick, in a good position for Costa Rica.
Wasted opportunity for Costa Rica as Bolanos' free-kick lands comfortably into the grasp of Cillessen.
Tejeda is fouled by van Persie 35 yards from goal, and that man Bolanos is standing over the ball again...
The Dutch give the ball away in the midfield and Martins Indi puts in a late challenge to give away a free-kick on the half way line. Been a sloppy first-half from the defender so far.
Replays show that Depay's effort was rather tame, and the PSV man will be disappointed he didn't add more conviction into his effort.
The Netherlands break on the counter and the ball is fed through to Depay, whose drilled effort is palmed away confidently by Navas. Another good save from one of Costa Rica's key men.
Bolanos curls it towards Borges, but the ball just narrowly evades the midfielder's head and it flies out for a goal kick to the Netherlands.
The throw in finds Ruiz, who's brought to the ground by Sneijder on the byline. Good opportunity for Bolanos to whip it into the area...
Martins Indi tries to find Kuyt on the right-hand side, but plays a very poor pass which goes straight out of play for a throw-in deep inside the Dutch half.
The Dutch are guilty of another offside, which van Persie, who was six yards out, will have been relieved to see as he completely miskicked Kuyt's through ball.
Sneijder plays a sumptuous ball over the top to Depay, but the winger is marginally offside. Sneijder showing glimpses of his playmaker tendancies.
Some really neat intricate play from the Dutch there. Jorge Luis Pinto will be concerned at the gaping holes his defence left for van Persie and co. Remains 0-0.
DOUBLE CHANCE! Kuyt picks out Depay on the edge of the area with a wonderful pass, and the PSV man slips it into van Persie who's one-on-one with Navas, but the Man United man hits it straight at the keeper. The ball falls to Sneijder, but his tame 20 yard effort is gathered up easily. Two big chances.
Gamboa is released on the right-hand side and tries to play a low, driven ball into the area but it lands right into Vlaar's path who clears the ball away from danger.
Sneijder drops deeper into midfield as the Dutch try to quicken up their game, which has been rather lethargic so far.
A few misplaced passes from both sides so far. Netherlands look content to break on the counter, while Costa Rica look sturdy in their set-up. Will be interesting to see who caves in first...
De Vrij carelessly gifts the ball to Borges who sprints towards goal, but a poor touch gives the opportunity for Blind to help out his defence, sweep up any danger and clear.
Van Persie touches the ball off to Kuyt on the right-hand side, but the former Liverpool man's delivery has no conviction and floats away from danger.
Once again, the Netherlands' counter attacking threat is clear to see as Costa Rica concede possession and van Persie breaks away. Outside Navas' area, van Persie looks to find Depay but Umana intercepts well. Good defending.
Costa Rica's longest spell of possession so far as their midfield keep the ball with some promise.
Great play from Gamboa as he dances past a couple of Dutch challenges and drills in a dangerous ball into the area, but there's no Costa Rica player to take advantage and Vlaar manages to sniff out the danger.
Early indications suggest that the Dutch are playing a 3-4-3 formation, with Depay operating as a left winger.
A long ball from Martins Indi is misjudged by Diaz and the ball comes to an unmarked Robben on the right-hand side, but the Bayern Munich man can't take advantage as Costa Rica get back in numbers to nullify the threat.
Disappointing delivery from the corner, as Robben fails to clear the first man and Costa Rica manage to clear the danger.
Excellent play from Robben who evades a number of Costa Rican challenges and plays the ball of Gonzalez for a corner to Netherlands.
Robben bursts on the counter attack and feeds the ball to Depay on the left-wing, who delivers a deep ball into van Persie - who is eventually flagged offside. A brief sign of Robben's explosive pace.
Netherlands with most of the possession so far, albeit at the back with Martins Indi and Vlaar exchanged a number of short passes.
Campbell makes a darting run into the area and Ruiz's free-kick aims to find the former Fulham man, but it's an inaccurate delivery and it sails out for a goal-kick.
Bolanos is blocked just over the half-way line by de Vrij, and the referee awards Costa Rica a free-kick. No yellow card, either.
Patient play from Costa Rica at the back, but they eventually try and force a 50 yard ball through to Campbell and Gonzalez's pass is wildly over-hit.
Gamboa almost gifts the ball to Van Persie on the edge of the Costa Rican area, but Umana gets in first and clears the ball to safety. Rapid start from the Dutch.
Costa Rica get us underway!
Got another prediction for you, and this time it's from Mattie Rance (@mattierance) who says: Holland to win 3-0. Robben, van Persie and Kuyt all to score for the Dutch.
Just under ten minutes to go, and both teams are out on the pitch and are preparing for their national anthems. A cruical clash in Salvador awaits!
Nile's tweeted in, and he thinks it'll be a tight encounter too: "I think it'll be closer than people think! 1-0 to Holland. RVP the scorer."
Our friends over at Sky Bet have some price boosts available for tonight's match. Cristian Bolanos to score first has been boosted from 22/1 to 25/1, while Costa Rica to win 1-0 has changed from 12/1 to 14/1. If you fancy the Dutch to win 3-0, the odds have been boosted from 9/1 to 10/1.
Thanks to Warren Palmer (@Warrendinho) who reckons an upset is on the cards: "I think Costa Rica could spring a surprise tonight after extra time and penalties for me."
Next up is Finlay Jack, who's emailed in with his prediction: "I think that this game will be too tough for Costa Rica, Netherlands' attack is simply too strong for the Costa Rican defence. 3-0 Netherlands, RvP (2) & Robben."
Quickest off the mark is Chris Green, who's emailed in: "Netherlands to win 2-1, with Robben getting a brace." Do you agree or disagree with Chris? We still have plenty of time to hear from you.
The omens aren't great for Costa Rica, who have beaten just one European side in their last seven encounters with teams from that continent, though this did come against Italy earlier in the World Cup (D3 L3).
The Netherlands have now turned their last four World Cup games in which they fell behind in regular time (90 mins, not inc. ET) into a victories, while seven different players have scored for Louis van Gaal's side at this World Cup.
Netherlands have won 10 of their last 11 World Cup matches, with the only blip in this run being their 2010 final defeat against Spain, while Costa Rica became the first CONCACAF team since the USA in 2002 to reach the quarter-final phase of the World Cup.
In preparation for tonight's massive game, our friends at Opta have sent us some statistics to whet the appetite...
Expecting a fascinating encounter tonight, with both sides performing exceptionally throughout this incredible World Cup. Will Costa Rica surprise us all again? Or will the Netherlands put in another superb performance? Predictions, as ever, are warmly welcomed and you can contact me via email: email@example.com or by Twitter @davidalexbowers.
Costa Rica coach Jorge Luis Pinto makes one change to the team that kicked off against Greece six days ago. Oscar Duarte is suspended after being sent off in Recife, so Johnny Acosta comes into the rearguard.
Costa Rica team (5-4-1): Navas; Gamboa, Umana, Gonzalez, Acosta, Diaz; Ruiz (c), Borges, Tejeda, Bolanos; Campbell.
That Dutch line-up is as expected from coach Louis van Gaal, who makes two changes to the side that began the 2-1 round-of-16 win over Mexico in Fortaleza last Sunday. Enforcer Nigel de Jong is out for the rest of the tournament with a groin injury, so Daley Blind moves into central midfield and Bruno Martins Indi returns to the centre-back trio. Paul Verhaegh drops to the bench to accommodate Memphis Depay starting on the left, with Dirk Kuyt shifting across to the right flank.
Netherlands team (4-3-1-2): Cillessen; De Vrij, Vlaar, Martins Indi; Kuyt, Wijnaldum, Blind, Depay; Sneijder; van Persie (c), Robben.
The starting line-ups have been announced...
Welcome along to our live coverage of the fourth and final World Cup quarter-final as the Netherlands face Costa Rica at the Arena Fonte Nova in Salvador.
