Patrice Evra insists Arsenal will provide a stern test for Manchester United despite their current poor run of form.
Sir Alex Ferguson's men will arrive at the Emirates Stadium on Sunday knowing a win would go a long way toward sealing the league title.
The Gunners have won just once in their last seven, a slump that has seen them seemingly drop out of contention in the title race at a crucial time in the season.
Yet, despite a run of poor results, Evra believes that Arsene Wenger's side will prove a dangerous prospect who, now nine points off the lead, have nothing to lose.
"You have to fear the wounded animal," said the full-back.
"It is all or nothing for Arsenal so that is a danger. They will want to show they can still win the title.
"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."
With United taking a comfortable 2-0 away win in their Champions League semi-final first leg at Schalke, attention can fully switch to domestic matters as the league leaders still pursue a double.
Four games remain in the run-in, but with the Red Devils set to meet nearest rivals Chelsea on 8th May, Evra knows it is vital his team get something out of their trip to North London.
"Sunday is a massive game for us. It is a great opportunity. There is still a lot of pressure on us," he added.
"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."
