5 players who will have a definitive say in the Arsenal vs Manchester United match

#3 Alex Oxlade-Chamberlain

The Englishman has done well in the wing-back role for Arsenal

Arsenal's player of the month for April, Ox's Man of the Match performance was decisive in Arsenal's victory against Manchester City at Wembley. Pinning Clichy in his own half, the Englishman provided more crosses (8) than any other Arsenal player, including the one that set up Nacho Monreal's equaliser.

“I feel that this wingback role has suited him well,” Wenger said recently. “First of all, he can use well his power. And it suits him well because he is facing the game when he gets the ball. I think he looks to be comfortable when he is running at people and when he has the ball at his feet.”

That was a good way to sum up Ox's increasingly influential performances as a wingback in Arsenal's latest 3-4-3 system.

With Luke Shaw's injury, United's option at left back is likely to be Matteo Darmian or a makeshift left back in Ashley Young. Either way, Shaw's injury means that Ox will have opportunities to raid the flank with his pace and power. Darmian will require help from the winger ahead of him – and whether Mourinho picks Martial or Lingard for that role will have a huge role to play in the result.
