Manchester United boss Sir Alex Ferguson says new signing Wilfried Zaha is one for the future.

Ferguson has told United supporters not to expect too much too soon from Crystal Palace loan returnee Zaha.

He said: "We like to sign young players with potential.

"We can develop players well as we have proved many times so hopefully the boy will enjoy it coming here.

"He's a winger, only a young lad of 20, so we will see."
