Hello and welcome to our LIVE coverage of Barcelona and Bayer Leverkusen's Champions League last-16 second leg at Camp Nou, with Barca leading 3-1 from the first leg.

Pique misses a header to let Kiessling in, but the Germany forward has too much to do and his cross doesn't get past Mascherano.

Pique manhandles Pique around 30 yards out, to the Leverkusen left. Castro to curl it in with his right... headed away by Cesc of all people.

Fabregas is in down the right this time but his cross, searching for Messi, is too close to Leno.

Mascherano lofts a ball into the channel but it's too high for Alves.

That was Messi's eighth goal in the Champions League this season. 11 more and he'll be Barca's all-time top scorer. And he's still only 12!

Great clearance from Pique, swivelling to slide it away as Augusto was set to pounce. Barcelona counter and Messi has sprung the offside trap, he's clean through and with the keeper rushing out the cheeky little so-and-so scoops a chipped left-foot finish over him and in! The impudence! Played onside by Kadlec as he checked his run diagonally across halfway. 1-0 Barca, 4-1 aggregate.

Meanwhile Iniesta tries a cute through ball but Castro intercepts. Back with Messi, now Iniesta on the left facing Castro. Slowly slowly from Barca...

Well the marking was poor from Leverkusen there, the ball wasn't even high on to the 6'3" Pique's head; he had to stoop into the flick, making Leno's save all the better.

Xavi will swing this in AND IT'S A BEAUTY AS PIQUE MEETS IT WITH THE HEADER BUT A SUPER PARRY BY LENO!

Iniesta is sent to the dirt by Castro, the Spaniard asking for a card as it was a rather cynical trip by the Leverkusen man.

Rolfes tries to dribble in down the left but that's not what he's paid for and Barca clear. Now Adriano has a chance edge of box but he shoots against Toprak.

Mascherano argues the toss with the ref after he is adjudged to have fouled Derdiyok. A good six or seven inches between that pair, the striker dwarfing the defender.

Augusto appears to be tripped on the edge of the box but Rolfes has a chance to shoot so the ref plays on: his effort hits Busquets though and Barca survive that mini-scare.

Barca counter but the backheel from Iniesta does not come off and the ball is sailed into the arms of Leno.

Barca coolly play it around at the back, Valdes and Mascherano cold as ice under pressure.

Messi on the ball, space and options and he looks wide left to Cesc. His cross is too high, too deep though and it lands behind Alves.

Derdiyok chests the ball down, now Kiessling on it but he handles and Barca have a free-kick.

Vital intervention from Schwaab as Alves sent a cross to Messi! Rolfes completes the clearance.

Messi almost releases Alves but the pass is intercepted by Toprak.

Swarming break from Barca but Alves's low cross from the right is behind the arriving Pedro and Messi and Leverkusen clear.

Free-kick to Barca then, around 25 yards out, a touch to the left... Xavi to take but he spins it high and wide.
