Manchester United boss Sir Alex Ferguson expects the title race to remain tight.

Victory over Liverpool moved United four points clear of Chelsea.

But Fergie said: "We're at the stage of the season where winning is the name of the game. We have been very consistent in the last few months.

"I don't think anyone's getting away. We are all knocking on the door.

"But I think that with Nemanja Vidic and Rio Ferdinand looking fresh, after being out for most of the season, it gives us a great opportunity."
