Shocking Arsenal defending nearly sees Bale and Lennon pick up on loose balls, before six minutes of added time is announced.
Walcott's decent effort has Lloris scrambling, but it drifts narrowly wide of the near post and the chances are running out for Arsenal to equalise.

87 Dembele hobbles off, adding to the extra time somewhat, before being replaced by Livermore.
Dembele tackles Wilshere, which looked fairly inoccuous, but the Spurs midfielder goes down painfully and it's his left leg which is currently being tended to by Spurs' physios.
Ramsey and Walcott lead the line down the right, before Rosicky crosses in, with Vertonghen's clearance falling to Giroud whose woeful effort flies into the fans.
Bale's free-kick 40-yards out carries a punch, but safe hands from Szczesny prevents the ball spilling out for any potential rebounds.
The corner comes to nothing for Arsenal, but the other end Szczesny shows his composure to deny Defoe near the byline, calmly heading the ball out of play.
A golden chance for Arsenal this time, with Ramsey set free by Rosicky, firing across goal with a crucial deflection from Assou-Ekotto steering it out for a corner.

Bale stings the arms of Szczesny, firing a volley on goal from just inside the penalty area after a prolonged period of pressure from a Spurs corner. It's turning into quite a cracker at White Hart Lane now!
Lennon is found on the right by Parker, whose dancing feet mesmerise Monreal, before his drive across goal is met by the outstretched foot of Vermaelen.
This time it's Defoe who comes close, with Wilshere seeing the ball stolen from him by Bale as the Spurs striker drags an effort wide from 20 yards. Two great chances in quick succession for the hosts.
Massive, massive chance for Tottenham, as Defoe feeds in Sigurdsson who selflessly plays the ball square with only Mertesacker near him when the goal was gaping.
Dawson positions himself well to head away as Spurs look to get back on the attack on the break before the ball ends up back with Arsenal.

Tensions threaten to boil over as Arsenal decline to play the ball out of play while Adebayor was injured, and Dawson is reprimanded as a result for his role in the exchange.

60 Jenkinson is hauled off for Arsenal, with Rosicky the man entering the fray.
What a chance for Spurs. Dembele's superb run and pass sets away Assou-Ekotto, but as he finds Bale at the far post, the in-form winger fires well into the stands.
Giroud leaps for the ball but falls awkwardly under Dawson, laying in some distress as a result while the Arsenal medics attend to the striker.
From a Spurs corner, Dembele hacks the ball back into the danger area, but Bale is caught yards offside when he picks it up and the attack comes to an end.
Szczesny sprints off his line to deny Adebayor reaching Bale's through ball, with both teams looking dangerous now whenever they go on the offensive.
Arteta finds Ramsey on the left, where he tormented Walker to win a free-kick before, but this time the Spurs left-back does better and only concedes a throw-in.
Nervy moments for Spurs, as Lloris initially does tremendously to cut out Jenkinson's delivery, before spilling it slightly as no Arsenal player looks up to capitalise.
Vetonghen hacks away from Wilshere's delivery into the centre of the penalty box, before Monreal unleashes a furious drive that swings away from goal. This is much better from the Gunners now.

Lewis Pacey is a man wanting answers. He writes: "Having been told for the last few years that fourth-place is as good as a trophy, what does Wenger do when he slips 7 points behind Spurs and 5 behind fourth-placed Chelsea? Us Gooners are interested in the answer!"
Gunners fans seem to be quite weary after that 45 minutes, and Carl Fletcher leads the line, writing: "For all Arsenal's passing being 2-0 down proves we aren't good enough any more. I'm hoping for a comeback but not optimistic!"
Two goals in three minutes see Spurs ahead at the break, and Arsene Wenger will surely have harsh words for his defenders in the Gunners' dressing room. Send your second half predictions to firstname.lastname@example.org or tweet @JWoodfield365

Tottenham 2 Arsenal 0. It's a horrible goal to concede from Arsenal, who aren't happy as Cazorla was left on the floor as Spurs attacked, but as Monreal pushes up, Lennon creeps in behind to meet Parker's ball, taking the ball around Szczesny before slotting it home.
39 GOAL! Lennon makes it 2-0!
Tottenham 1 Arsenal 0. Sigurdsson's through ball is far more precise this time, expertly playing in Bale behind Arsenal's centre-backs who naturally finishes with aplomb. First blood in the derby to Spurs!

A storming challenge from Vermaelen sees the ball wrangled away from Parker, who went down heavily but it seemed to be a fair tackle.

Spurs enjoy time on the ball, without progressing foo far forward for the time being as Lloris ends up booting the ball upfield which Dembele collects.

Vermaelen's chip over the top finds Giroud, but he sets off a tad early and the linesman's flag is raised as a result. Tottenham free-kick.

Giroud hussles Parker, regaining possession for his side as Assou-Ekotto slides in to prevent Walcott breaking away down the right.
Wilshere leads Arsenal forward, before Ramsey is closed down which earns his side a throw-in. From that throw, Wilshere is denied the chance to shoot as Vertonghen gets the tackle in.
Sigurdsson flies into Jenkinson, conceding a free-kick with that sliding challenge, and as Wilshere delivers, Vertonghen is required to head away for Spurs.
Dawson charges in to get his head on the ball, but the offside flag is raised and it's an Arsenal free-kick.
A tackle by Arteta on Lennon is eventually brought back for a free-kick by Clattenburg, and Bale will line up to take it.
Tottenham kick off and get the action started.
The players are out on the pitch having been met be a deafening ovation, and we're now moments away from getting the North London derby underway.
Some betting news from our friends at Sky Bet now. Spurs are 13/10 favs with Arsenal 2/1 and the draw 12/5. Punters have been torn over who will win but are backing Bale to score in their droves.
Chris Dow is pragmatic before kick-off, writing: "I'm an Arsenal boy, but can see Spurs running the show this afternoon. I reckon 4-2 for Tottenham is a fair shout - Arsenal's defence lately, derby or not, has been woeful."
So of course the name on everybody's lips ahead of today's game is Gareth Bale, especially after his sensational winner against West Ham on Monday night. However, given that Andre Villas-Boas' last two games against Arsenal with Chelsea and Tottenham have seen his sides concede 10 goals overall, it may end up being Spurs' defence that is required to save the day if they are to emerge victorious this afternoon.
Specifics now from Justin, who writes: "Arsenal to win 5-2, Bale to score first and Tottenham to lead first half, but expect a comeback special from the boys in red with Wilshere being the man to win us the game! COYG!"
Russel Green gets us underway, writing: "This is a big chance to gain points and push for the third position in the league. Spurs are slow starters at home and we need to make sure we are ready from the start. To be fair I see draw written all over this one."
