Michael Carrick believes Manchester United have been forced to rely on their survival instincts rather too often this season.
Yet again, the Red Devils were forced to come from behind on Wednesday, with Carrick grabbing the late winner to overcome Wigan. It leaves United a point away from clinching an 18th championship, which they will secure in front of their own fans on Saturday if they avoid defeat to Arsenal.
"You are not going to play your best every week," Carrick said. "We have been playing great recently but we have come from behind too many times this season. If we do win it, we will have done it the hard way."
With Darren Fletcher, Park Ji-sung and Ryan Giggs among those ready to come back into United's starting line-up, plus Rio Ferdinand if the England defender overcomes a calf problem, Ferguson once again has plenty of options at his disposal.
It is not an uncommon occurrence for Arsenal to win at Old Trafford. Indeed they have emerged victorious on three of their last 12 visits, and drawn on two more occasions.
However, Arsene Wenger's men might struggle to hold their hosts on this occasion, given the importance of avoiding defeat and the battering they have taken over the past week, when a Champions League beating by United was followed by an even worse mauling by Chelsea.
"We have got to respect Arsenal because they are a good side and we know they can hurt teams," said Carrick.
"Over the last couple of games we have had the better of them but that doesn't mean anything tomorrow (Saturday).
"We have to start again because I am sure they will want a bit of revenge."
