Manchester United defender Nemanja Vidic says it's important they go into Sunday's clash at Liverpool not over-confident.

Whilst United go into the game on the back of a Champions League win at CSKA Moscow - Liverpool having suffered a demoralising home loss to Lyon - Vidic insists the game is no foregone conclusion.

The Serbia international said: "It is not good to have too much confidence but it is good to have won before the game against Liverpool.

"We believe in the squad and each other and this is important."
