Manchester United defender Nemanja Vidic has said that the Red Devils are back to their best after their 6-1 derby defeat to rivals Manchester City.

United bounced back from the Old Trafford drubbing to beat Aldershot 3-0 in the Carling Cup last week and they took a 1-0 victory at Everton on Saturday.

"It was important to show the 6-1 didn't affect the players and I think we showed that at Everton," Vidic said.

"It was important to defend like a team and get back to playing as a team. In the last 20 minutes against City we didn't do that.

"When you lose a derby, especially by that score-line, it is difficult to take. But we have shown character."

Vidic said that it was important that United didn't dwell on the defeat as they went forward.

"Hopefully we can prove that the derby was just one bad day.

"We haven't come to training with our heads down. We have worked harder because we want to play better. This is the right mentality to have.

"Losing that game was difficult but it's important to look forward. Even when you win you can't spend time celebrating, you have to focus on the next game."

United take on Romanian team Otelul Galati in the Champions League on Wednesday.
