Alex Oxlade-Chamberlain has told his Arsenal teammates to draw on their FA Cup win at Manchester United as motivation for repeating the feat at Old Trafford on Sunday.
The Gunners ended a nine-year barren spell at the Theatre of Dreams in March by beating United 2-1 to progress into the quarter-finals of the competition.
Arsene Wenger's side make the same trip again this weekend knowing that victory would see them finish at least third and avoid a Champions League playoff in August.
"You can definitely take confidence from any win at Old Trafford," Oxlade-Chamberlain told Arsenal's official website. "It's a hard place to go and win, especially against a good Manchester United side.
"It will be a tough game but we can take positives from our last trip there in the FA Cup and the win that we managed to come away with. That was in a high-pressured environment, as we had to win that to get through to the next round of the cup. To do it at Old Trafford is a big achievement.
"We go into every game trying to win and it hadn't gone that way for us [in the past], but in the two Manchester fixtures this season we've done well and come away with two wins. It's other people that will analyse it and say that we've stepped over a [psychological] hurdle. We just go into it and focus, as we do with every game, on coming away with the win."
Danny Welbeck, who swapped United for the North Londoners in September, came back to haunt his former club by grabbing the winning goal that night.
