Patrice Evra has warned Manchester United to beware the wounded animal at the Emirates Stadium on Sunday.

With a place in next month's Champions League final at Wembley virtually assured following their win over Schalke, United's main focus is now on regaining the Premier League title. They lead the table by six points ahead with four games to go and still have to play their closest challengers, Chelsea, so much now rests on this weekend's match.

Arsenal have all but blown their own title hopes having taken just two points from their past three games, but Evra said: "You have to fear the wounded animal. It is all or nothing for Arsenal so that is a danger. They will want to show they can still win the title."

Arsenal's sudden collapse appears to bear out Evra's controversial statement earlier this season that manager Arsène Wenger needs to decide whether he is managing a football club or a finishing school for young players. However the 29-year-old has warned against United believing Sunday will be easy.

"We have a good record at Arsenal but statistics can change so quickly. Everyone used to say how Arsenal kept losing to Chelsea and then they beat them. We kept losing at Stamford Bridge but won there in the Champions League.

"Our record at the Emirates will hurt them and they will want to do something about it."

He added: "Sunday is a massive game for us. It is a great opportunity. There is still a lot of pressure on us. If we lose and Chelsea have beaten Tottenham on Saturday, they will only be three points behind and they have to come to Manchester. That is what we have to think about now."
