Chelsea midfielder Willian is adamant they can upset Barcelona in their Champions League clash.

Chelsea warmed up for the first-leg with an FA Cup win over Hull City on Friday.

Willian, who scored twice, said: "Football is all about results.

"When you win everything is fine, when you lose, no. We always try to work hard and improve ourselves and we have to continue like that.

"We play for Chelsea, we always want to win titles. In the Champions League we know it's going to be a difficult game but we are Chelsea, we know we can win the game. We have to prepare and no doubt it will be a massive game."
