The whistle goes for full-time and Wales have been beaten 2-0 by an impressive Bosnia side. Coleman will not have been too pleased with the performance and now has just a few weeks to get his men ready for their first World Cup qualifier.
Bosnia are finishing the game on the front foot as Sesar lets fly from 20 yards with an effort that flies high and wide of Myhill's goal.
88 Crofts is replaced by Earnshaw and that means we have now had the maximum number of substitutions allowed for a friendly, 12.
87 Bosnia make their final two permitted changes, with Vranjes and Vranjic coming on for Mujdza and Zahirovic.
Dzeko's finishing is the only thing that has let him down tonight, as he skips away from a couple of challenges before blazing high into the stands.
Perhaps sensing that they just need to work a bit harder to close this game out, Bosnia have regrouped over the past few minutes and look solid once again.
82 Sesar enters the fray for the final few minutes in place of the impressive Pjanic.
Wales have looked better since Bellamy came on and they will feel they still have a chance of salvaging something here, as Morison heads wide from close range.
78 Lynch has been granted a 12-minute cameo after being brought on for Blake.
Dzeko stings the palms of Myhill with a powerful shot from 20 yards, before players from both sides become involved in a bit of a row following a confrontation between Williams and Mujdza. The referee steps in and sorts it out quickly, with nobody punished.
Pjanic turns a volleyed effort over the crossbar from close range as Bosnia break forward in search of a third goal.
75 These substitutions are. Predictably, disrupting the flow of proceedings now, as the goalscorer Ibisevic makes way for Svraka.
Bellamy delivers a superb cross from a free-kick and the ball breaks for Ramsey, but he is surrounded by defenders and cannot get his shot away.
72 Pandza is replaced by Sunjic for Bosnia with a little under 20 minutes remaining.
70 Another double change for Wales, as Ricketts and Morison come on for Gunter and Vokes.
There are shouts for a penalty, from the crowd at least, as Pandza's arm comes into contact with the ball, but it would have been harsh to award a spot-kick as he could not have got it out of the way.
Ramsey tries to release Bellamy down the left wing but his touch is just too heavy and the ball drifts behind for a goal-kick.
Bellamy gets involved almost immediately and his introduction seems to have lifted the level of his team-mates, with Wales now trying to apply some pressure.
63 Bosnia respond with a change of their own, as Lulic makes way for Besic.
62 A huge cheer rings out around the stadium to greet the introduction of Bellamy as the first substitutions of the night are made. Also coming on is Robson-Kanu, with Bale and Church the men replaced.
Bale has shrugged off that earlier back scare and is in full flow once again as he surges down the right, beating Spahic for pace before sending over a fine cross that narrowly evades Vokes.
Bosnia really are playing some lovely stuff but they are being allowed to do so by a disappointing performance from Wales, as Dzeko and Pjanic link up to good effect in an advanced area once again.
Bale has to be escorted to the touchline after hurting his back in an awkward landing following an aerial challenge with Spahic, but he seems to be walking quite freely.
54 GOAL! More poor defending from Wales allows Pjanic to play in Stevanovic, who wanders unchallenged into the box before blasting a powerful shot past Myhill to make it 2-0 to Bosnia.
Salihovic delivers a menacing ball from the right that Myhill has to dive to reach, before Dzeko is flagged offside.
Dzeko may struggle to be a regular starter for Manchester City this season but he has impressed tonight, not only with his strength but also with his movement and technical ability.
Ibisevic gets away from his marker far too easily from a corner and neatly flicks the ball into the centre, but Wales survive.
Ramsey spreads the ball out to Gunter and then shows good vision to try and play in Church, but Mujdza stays alert and gets a crucial touch to deflect it to safety.
Bosnia quickly win their seventh corner of the game and Wales again struggle to deal with the danger, but on this occasion the referee spots an infringement and blows his whistle for a free-kick to the home side.
Bosnia kick things off in the second half and will be looking to keep up the intensity from the first half and protect their 1-0 advantage.
The half-time whistle goes and Wales are 1-0 down after an impressive display so far by Bosnia. Ibisevic grabbed the goal and has looked particularly lively, along with Pjanic and Dzeko. Bale has threatened at times for Wales but there is a lot of work for the hosts to do in the second half if they are to turn this around.
Ramsey produces a delightful piece of skill to wriggle between a couple of defenders and he is then brought down for a free-kick out wide.
Bale may be Wales' star performer but his latest effort is ambitious even by his standards as he rifles a long-range strike way off target.
At times in this first half it has looked like Wales need a ball of their own to play with as Bosnia are so good in possession, and a second ball temporarily makes its way onto the pitch before the referee halts play.
Pandza does well to head the ball clear under pressure from Bale as Wales try to get back on level terms before the interval.
Wales do not deal with the corner decisively and the ball bounces around in the box for a moment or two before Ibisevic heads over from 12 yards.
It briefly looked like Wales were building up a head of steam but Bosnia now seemed to have regained control with some slick passing, which ends with Dzeko firing a shot wide via a deflection.
Bale is really starting to purr now, as he skips away from his defender before pulling back a dangerous cross.
Bale does well again to draw a couple of defenders out of position with a dangerous run, allowing room for Ramsey to charge through the middle before seeing his shot blocked.
Bale is capable of conjuring something out of nothing and he nearly manages it as he controls a long pass from Williams before shooting from distance, but it is an easy save for Begovic.
Wales finally enjoy a decent spell of possession in midfield but they are not moving the ball as quickly as their opponents, with Vokes just caught offside from Allen's pass.
A couple of chances come and go for Bosnia in quick succession as Williams tackles Dzeko just as he is about to unleash a volley, before Ibisevic drags an effort wide after going past Taylor with a neat piece of skill.
Wales are struggling to get on the ball at the moment but they are given some breathing space as Salihovic fouls Allen to give away a free-kick.
Stevanovic and Ibisevic nearly combine for a second time but the striker this time fails to connect properly with another well-placed cut-back.
The goal has left the crowd quiet and they have had little opportunity to find their voice with Bosnia so dominant in possession.
21 GOAL! Bosnia take a deserved lead as Stevanovic capitalises on a mistake from Taylor at left-back to sprint down the wing and deliver a delightful low cross that Ibisevic slots coolly home.
Wales break up Bosnia's patient passing game with a couple of tough challenges, but they are struggling to get the likes of Bale involved at this stage.
There are appeals for handball in the Wales area as Pjanic hits the ball against Crofts, but if it did hit his arm it certainly did not look deliberate.
Dzeko heads against the crossbar from yet another corner and the ball loops up for Myhill to gather safely.
Another corner for Bosnia results in Lulic trying his luck with a volley that looks technically good but is driven well wide.
Players can sometimes still be searching for fitness at this time of year but Wales' three Olympians, not surprisingly, look especially sharp.
Bosnia are causing problems on the counter-attack and earn a corner, although Pandza then concedes a free-kick as he tries to win the aerial battle.
The ball falls to Allen from the corner and his shot is pushed onto the crossbar by a superb save from Begovic, with Bale unable to turn the rebound past the goalkeeper from a tight angle.
Bale bursts into life for the first time with a clever pass to release Allen, whose inviting low cross is cleared away for a corner.
Pjanic seems to be the set-piece specialist in the visiting team, as he takes a free-kick 25 yards out that is blocked behind for a corner, which he does not do much better with.
Bosnia have started brightly, with the talented Pjanic delivering a cross from the right that looks dangerous but does not pick out a team-mate in the centre.
There is a good atmosphere inside the ground even though the stadium is by no means full, and Wales will hope to use the fans as inspiration.
Wales win a free-kick inside Bosnia territory and Bale decides to try and catch Begovic napping at his near post by going for goal rather than curling over a cross, but his 35-yard effort flies wide.
Bosnia almost take the lead straight away as Williams dwells on the ball and is dispossessed by Dzeko, who draws a fine diving save from Myhill with a powerful shot from inside the area.
Wales get the game started in Llanelli and let us hope for an exciting match that is full of attacking football.
Wales: Myhill, Gunter, Blake, Williams, Taylor, Bale, Ramsey, Allen, Crofts, Church, Vokes. Subs: Brown, Lynch, Ricketts, Matthews, Ledley, Edwards, Bellamy, Morison, Earnshaw, Robson-Kanu, Fon Williams.
Bosnia-Herzegovina: Begovic, Pandza, Spahic, Mujdza, Salihovic, Pjanic, Zahirovic, Stevanovic, Lulic, Ibisevic, Dzeko. Subs: Avdukic, Sunjic, Vrancic, Besic, Svraka, Ognjen Vranjes, Sesar.
Edin Dzeko and Asmir Begovic are among the most familiar faces in the Bosnia squad and both have been handed starting roles tonight. For Wales, Gareth Bale is in the team for the first time since November of last year, but Craig Bellamy begins on the bench. Simon Church has been preferred to new Cardiff signing Bellamy while Sam Vokes leads the attack and Boaz Myhill lines up in goal.
Bosnia-Herzegovina are, of course, gearing up for their own World Cup qualifying campaign and will fancy their chances of making it through to their first major tournament after losing out to Portugal in a play-off for Euro 2012. Their group for the World Cup does not look too bad, with Greece and Slovakia the main threats, and Safet Susic will want to go into next month's matches against Liechtenstein and Latvia with some momentum.

Wales face a tough road to the World Cup in Brazil after being drawn in a qualifying group alongside Croatia, Serbia, Belgium, Scotland and Macedonia, but they made such great progress under the late Gary Speed that they will believe it is possible. Chris Coleman's first competitive match in charge will come next month against Belgium and he will be looking for a positive performance in tonight's game at Parc y Scarlets in Llanelli.
Good evening and welcome to our minute-by-minute commentary of Wales' international friendly against Bosnia-Herzegovina. The timing of these games may not be to everyone's liking, particularly club managers, but this is an important stepping stone for Wales as they build for the future.
