One team who know what it takes to beat Barcelona at Camp Nou are Atletico Madrid, who have won on their past two visits in La Liga. Their captain, Peter Luccin, explained the secret of his side's success in the Spanish champions' backyard.

"The most important thing is to make sure you play with a very solid block at the back, keeping the players close together and denying them space. The midfield has to play very close to the back four and not let Barcelona get in behind. Then you have to look to play them on the break.

"Our plan was, essentially, to sit back, invite them on to us and then break quickly. Chelsea are a conservative team who like to counterattack, breaking quickly into space, and that will suit them at the Camp Nou.

"However, it will be harder for them than it was for us because they have the disadvantage of being a goal down from the first leg, and that should mean that Barcelona will also sit back in defence and not concede so much space into which they can run.

"Nonetheless, Barcelona are such an attacking team that they will still go forward and commit a lot of men to attack. Chelsea have to be ready to spring a quick, early ball behind the midfield and run at their defence."
