Chelsea fullback Ashley Cole says there's great belief inside the squad of success at Barcelona.
Cole says Chelsea are going into the match full of self-belief that they can get the result they need to progress to the final in Munich next month.
He said: "The first game did take a lot out of the players, not just physically but mentally as well. It is hard because you have to be concentrated for the full 90 minutes. I know we have other big games coming up this season but we are ready for them.
"We know we're a good team. When everyone is focused and determined to prove people wrong, the result showed last Wednesday that we can beat any team.
"So far the season is turning for us. The confidence is big and we just have to take it in to every game."
