He told chelseafc.com: "The best signing now would be Franck Ribéry because if I have one complaint about Chelsea's game it's that it is a bit slow at times. We have big players, strong players, beautiful players, but we miss having this pace.
"Having Joe Cole injured was a tremendous problem and I think somebody like Ribéry brings the pace. He gets the ball, turns and makes some movements and puts the defence in danger. I think Chelsea need a player like that if they want to be dangerous next year."
