It's all over at the Camp Nou, and Barcelona cruise through to the quarter-finals. A 4-0 victory was well-deserved, and they have sent a warning to the remaining sides that they are still THE major force in Europe. Thanks for joining us on Goal.com!!!!!!
Into stoppage time now.
Facing Barcelona on a night like this is virtually impossible, particularly with going two goals down in the space of 20 minutes. Stuttgart never ever looked likely of producing anything this evening.
Goal Bojan Krkic
GOOOOOALLLLLLLL!!!!!!!!!!!! It's number four, and Bojan nets with his first touch!!!!! Ibrahimovic slid the ball through and Bojan's first-time finish leaves Lehmann helpless outside of his area. His strike rounds off an impressive evening for the 2009 winners.
Substitution Andrés Iniesta Luján Bojan Krkic
Messi homes in on goal again, getting a break of the ball to find himself through on Lehmann, but his dinked finish drifts wide of the post. The only negative so far this evening from the diminutive genius.
Georg Niedermeier has been one of Stuttgart's most assured performers this evening, and he did extremely well to deny Messi when one-on-one with the striker.
Ibrahimovic flagged offside again, and this one looks to be a very poor decision, denying the Swede a much-needed goal.
Credit must go to Stuttgart for maintaining 100% effort in the face of their formidable opponents - they have tried to remain positive, and it is admirable given the gulf in class here.
Substitution Thierry Henry Gabriel Milito
Lehmann is up to his old tricks again, refusing to fetch the ball from the net, where Ibrahimovic put it from an offside position, and he ran the risk of receiving another yellow card from the referee, who looks to be losing patience.
A succession of tight offside decisions frustrate Barcelona's attempts to add to their lead, with Ibrahimovic particularly aggreived, but it remains 3-0.
A decent cross from the left leaves Dani Alves disorientated, and he takes no chances, knocking the ball behind.
Was that from the training ground? A deep corner to Iniesta is chipped back in from Iniesta, but Alves' header is neither on target nor into the path of Henry, and the ball drifts behind. Should have been number 4.
Substitution Pavel Pogrebnyak Ciprian Marica
HUUUYYYYY!!!!! A raking cross from Dani Alves finds Messi completely unmarked at the back post, and his downward is excellently saved by the outstretched hand of Lehmann. A superb save from the veteran.
The German side enjoy a rare foray forward, but Molinaro's cross is to no one in particular, and drifts harmlessly out of play.
The Swede has arrived to a thoroughly raptourous reception from the home fans. He has came in for criticism recently, but it appears his fans are well and truly behind him.
Substitution Busquets Zlatan Ibrahimovic
Zlatan Ibrahimovic is readying himself on the touchline, probably the last thing the Stuttgart players could have wished to see....
Sergio Busquets is currently receiving treatment, giving time to reflect on Messi's beautiful second goal of the match. Every time he touches the ball, a goal seems not too far away.
GOOOALLLLL!!!!!!!! It's that man again, Lionel Messi, and the superlatives to describe this player have ran out. A flick from Alves on the edge of the area, a turn, and a precision left foot shot past the hand of Lehmann gives Messi his 31st goal of the season. If the game wasn't already over, it is now. 3-0.
Stuttgart are playing the ball tentatively, perhaps scared to surrender the ball to Barcelona for fear of a counter attack. They will need to find inspiration from somewhere, and quickly.
HUUUUYYYY!!!!!! So close to a third from Barcelona. Messi, once again, times the pass to perfection but Toure drags his shot a foot wide of the post. He perhaps should have did better, and looks up ruefully.
Kuzmanovic lands a thumping kick to the leg of Messi and is booked. Messi looks a little shaken up but is soon up and getting on with the action.
Yellow Card Zdravko Kuzmanovic
Superb pressing of the ball from Barcelona, pushing die Schwaben all the way back to Lehmann in order to maintain possession.
It appears to be more of the same here, Stuttgart will have to commit more men forward eventually, but it will leave gaps that Barcelona are masters at exploiting.
Pedro whips in a teasing low cross, looking for Messi, but he is well marshalled on this occasion by Niedermeier, who blocks his advances.
Substitution Stefano Celozzi Timo Gebhart
We are back underway here at the Camp Nou, with Stuttgart having it all to do.
That is half time, stay with us to follow more action as the European champions look to book their place in the last 8!!!
Into stoppage time at the end of a straightforward half for the Catalan side.
Yellow Card Pavel Pogrebnyak
Barcelona are continuing to play possession football without any real penetration, because they are in a position to do so at the moment. It will take enterprise and desire from Stuttgart to change the current dynamic of the match.
Yellow Card Jens Lehmann
Jens Lehmann, as is so often the way, argues with the referee and earns himself a yellow card. He looks among the most frustrated players in the away side.
Barcelona seem content that their offensive work is done for the moment, everyone apart from Messi, that is. He burst forward once more, and chooses to play in Henry, but his pass is a little heavy and the former Arsenal man couldn't get on the end of it.
Barcelona win a free-kick 30 yards from goal, which is placed ominously by Dani Alves. However, the Brazilian's effort whizzes wide of goal.
Pre-match, Stuttgart coach Christian Gross was asked how to stop Lionel Messi, and he responded by saying, 'stop him getting the ball'. If only it were that easy, Christian...
At the moment, it doesn't look like Stuttgart really believe that a route back into this match is possible. Barcelona have moved back down through the gears, but it hasn't really affected their dominance.
Stuttgart enjoy a spell of possession, but the delivery into the area is atrocious. Their crossing and passing will have to substantially improve if they are to create anything like an opening in front of goal.
My eyes may have deceived me, but Lionel Messi just miscontrolled a pass. However he showed great workrate to try and win the ball back, and was unfortunate to be penalised for a foul.
Stuttgart need to ensure that this match does not slip away completely, to avoid this scoreline becoming embarrassing. Barcelona look incredibly comfortable, even this early in the contest.
Guardiola has a face of satisfaction on the touchline, his side are producing the kind of performance which was a regular occurance last season, but not so much this season. Perhaps they are clicking into gear at precisely the right time of the season, from their side of things.
GOOOOOOAAAAAAAALLLLLL!!!!!!! IT'S ALL TOO EASY!!!! 2-0 to Barcelona, and its another wondrous goal. Messi threads the needle, slipping the ball through to Toure, and his cutback lands at the feet of young Pedro who taps the ball home. The task facing Stuttgart now looks insurmountable.
Barcelona have only conceded 17 goals in La Liga this season, the best record from any of the major leagues in Europe, so the Germans face a difficult task to break them down. At the moment, they could do with getting a touch of the ball.....
Stuttgart are endeavouring to get back into the match quickly, despite their game plan being undone, but Barcelona with a lead are a formidable mistress, and they are stroking the ball around neatly at the moment.
We are truly witnessing a footballer at the peak of their powers at the moment, untouchable in every way. It was a wonder strike from the Argentine, and it has settled the nerves of the home fans. Stuttgart, though, hard to score anyway, so nothing has changed from their point of view.
GOOOALLLLLLL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! OOOOHHHHH, Wonderful Messi! He is quite simply from another world. He picked the ball up on the half way line, dribbled, ran, dipped, and struck a venomous left foot shot into the top corner of Lehmann's net. SENSATIONAL!!!!!!!! 1-0 BARCA!
Beautiful movement from Henry, skipping past through challenges, but drags his shot wide of the post. He looked fighting fit at the weekend when he arrived at half-time, and he looks up for it again here.
Messi with his first effort of the match. His radar was rarely off target at the weekend, as Valencia would testify, but his curling shot here is easily clutched by Lehmann, who looks set for a busy evening ahead.
A sniff of an opening for Stuttgart. The ball skips up and for a moment it seemed that Pogrebnyak was ready to pounce, but Alves covered superbly from full back to avert the danger.
Barca are applying pressure. Pedro has a pot shot from the edge of the area, but drags his effort wide. There is space for Barcelona, however, in the opening exchanges.
An early chance for the home side, with Henry and Messi linking well, but the Frenchman's shot is somewhat fumbled by Jens Lehmann for a corner, which comes to nothing.
Another notable absentee for Barcelona tonight is Xavi, who has failed to recover from a knock, and so Yaya Toure returns in the central midfield berth.
We are underway here in Catalonia.....
Team News: Ibrahimovic is only granted a place on the bench for Barcelona, with Pep Guardiola opting to use Thierry Henry through the centre flanked by Pedro, and of course Lionel Messi, fresh from Sunday's demolition of Valencia. For Stuttgart, Hleb gets a start against the club who own his contract, with Cacau and Pogrebnyak partnered up front.
Good evening and welcome to Goal.com's live coverage of Barcelona versus Stuttgart. The tie is evenly poised after Zlatan Ibrahimovic's equaliser in the first leg leaves the sides locked at 1-1, but the Blaugrana will be favourites in the imposing Camp Nou! Stay with us to follow the action!
