Manchester United boss Sir Alex Ferguson rates David Silva as Manchester City's main man.

Whether United do all right today and extend a record run of 19 consecutive home League wins could depend on how they cope with the elusive skills of David Silva and the threat they don't see coming.

Ferguson said: "We've been trying to work out who they are going to play against us because they've got so many options.

"I think Silva is the one who'll definitely play. He's been the best player for them this season. He's making them tick.

"But I think the important thing for us is to not over-worry about that part and concentrate on our own game. I trust my players. They've been there many, many times. It's not a problem for young players as long as they have the temperament and our young players do."
