Arsenal boss Mikel Arteta feels they've learned from defeat at Manchester United earlier this season.
He feels that loss proved to be a valuable learning experience, as they have since shown plenty of resilience and composure to see out difficult moments in games to come away with all three points time and again.
Speaking in his pre-match press conference, he said: There were some important lessons about that game and the reason why we lost it. In many moments we were in total control of the day.
But we know that's one of the qualities of Man United - when you are in control of the match, the game gets away from you because they have so much individual talent, good organisation and many ways to create problems.
'We'll have to be at our best to win on Sunday."
