Manchester United boss Sir Alex Ferguson delighted to have Nemanja Vidic back

Sir Alex Ferguson admits Nemanja Vidic's timely return from injury is a 'big bonus' for Manchester United.

Pressure

He added: "He's under pressure isn't he? But he'll make a difference, absolutely. He gives us the options. "And to have senior players like that, it's helpful."
