Chelsea boss Andre Villas-Boas was unhappy with fans jeering Rio Ferdinand and Patrice Evra throughout his side's 3-3 draw against Manchester United.

Ferdinand and Evra were booed almost every time they touched the ball at Stamford Bridge on Sunday.

Villas-Boas said: "You don't expect opposing fans to cheer your players."

He added: "This is a normal situation in the Premier League.

"You have to condemn it when there is discriminatory, aggressive behaviour.

"We know the situations. We know we have to play a part.

"If we want to push on this sequence of events to extend in the future, it's up to us. It's up to me and it's up to you in the press.

"If you want to give importance to situations like this, if you let people take responsibility, assume responsibility and the fans and the knowledge that maybe what they were doing makes no sense, it's better but to try to prevaricate isn't right."
