Manchester United boss Sir Alex Ferguson has no doubts about Nemanja Vidic going into tomorrow's clash with Liverpool.

Vidic has been sent off in his past three games against Liverpool.

But Ferguson said: "The two at Anfield were definitely influenced by the crowd and the Liverpool players. I have looked at them again. I don't think it will affect him this time. With Rio Ferdinand and Vidic coming back, you can see a much greater presence at the back now."
