Manchester United v Arsenal: Alex Oxlade-Chamberlain backs teammates to shine at Old Trafford on Sunday

Arsenal midfielder Alex Oxlade-Chamberlain believes that the Gunners can gain confidence from their win at Old Trafford earlier in the season ahead of their trip to Manchester on Sunday, 17 May.

The Englishman is currently out injured and is facing a race against time to be fit before the end of the season, but he is confident that his teammates can get the job done and become only the fourth team in history to beat Manchester United twice at home in one season.

The north London club beat the Red Devils 2-1 at Old Trafford in February in the quarter-finals of the FA Cup with goals from Nacho Monreal and Danny Welbeck either side of a Wayne Rooney strike.

This has supposedly given the players a lot of confidence going into the Premier League clash against the 20-time English champions.

"You can definitely take confidence from any win at Old Trafford. It's a hard place to go and win, especially against a good Manchester United side," Oxlade-Chamberlain told Arsenal's official site.

"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," the Three Lions midfielder explained.

"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," the former Southampton player added.
