Manchester City winger David Silva admits they must focus only on tonight's Champions League clash with Villarreal.

Silva has stressed the need to put thoughts of next weekend's eagerly-anticipated derby against Manchester United at Old Trafford to one side for now.

He said: "The weekend is a very important game against Manchester United and we are aware we need the points in that one too because they are right behind us in the league.

"But for now we are just concentrating everything on tomorrow."
