Arsenal boss Arsene Wenger has been thrilled with the recent performances of Alex Oxlade-Chamberlain at wing-back.

The attacking midfielder has been operating on the right side of a four-man midfield in the past two matches with Wenger having deployed a 3-4-2-1 formation.

While 'The Ox' has impressed in yet another new role this season, Wenger says the future of the 23-year-old certainly remains in central midfield.

"It will be decided in the summer - we have a big job to do in the summer," said Wenger, according to Arsenal.com.

"He's done very well at wing-back.

"In the future, on long term, he will play in central midfield. What he is doing at the moment will help him to be a successful central midfielder as well. But at the moment I feel that this wing-back role has suited him well.

"First of all he can use well his power. And it suits him well as well because he is facing the game when he gets the ball. It's a different kind of game to be marked by somebody, get rid, turn and go forward, or to face the game. I think he looks to be comfortable when he is running at people and when he has the ball at his feet.

"When we speak about systems, some systems give a little advantage to some players because it just suits them a little bit better, comforts their qualities. He has maybe benefited from it.

"I think Alex is one of the players who has developed very well mentally. He is more positive, more confident, more mature. He was sometimes a bit negative with his own performances. And I think on that front he is much better now."
