Benfica winger Nicolas Gaitan has sought to wind up Chelsea strikers Didier Drogba and Fernando Torres ahead of their Champions League clash.

Gaitan is confident Benfica will claim their second English scalp of this season's Champions League after helping to dump out Manchester United at the group stage.

The Argentina star said: "I think there is an anxiety in Chelsea by the lack of goals from Torres and Drogba.

"We can exploit that and even though it will be difficult to stop them, it is possible and I have confidence we will keep a clean sheet."
