Arsene Wenger has admitted that he is unsure whether Theo Walcott would remain at Arsenal beyond the summer transfer window. The forward has seen his role limited at the Emirates and lack of playing time has raised concerns over his future at the club.

The 27-year-old missed part of the season due to injury and since his return, Walcott has failed to cement his place in the starting lineup. He has lost his place to Danny Welbeck and Alex Iwobi as the two have impressed for the north London club in recent games.

Walcott's last start in the Premier League came during his side's 3-2 defeat to Manchester United on 28 February. He has fallen out of favour at Arsenal and Wenger has urged him to turn his form around to prove his worth.

Meanwhile, former Gunners striker Charlie Nicholas has said that Manchester United, Chelsea and Liverpool could consider an approach for Walcott after the end of this ongoing campaign. Wenger believes that the England international's future at the club remains uncertain after suggesting the former Southampton man has gone through a bad phase.

"I don't know yet," Wenger told Sky Sports when he was asked whether Walcott could leave Arsenal in the summer.

"I'm not in transfer mode at the moment, but I think he has gone through a bad spell. He has responded very well, because he said: 'Okay, I will work harder and more'. Even when he comes on now, you see he is motivated and focused. Let's see how well he finishes the season now," he said.

"You have the emergence of a guy like Iwobi. But the players that did not play [against West Brom]: Santi Cazorla, Mikel Arteta, Mathieu Flamini, Jack Wilshere, Alex Oxlade-Chamberlain, and I forget a few that weren't even in the squad.

"All these players will be frustrated, or the guys who go out will be frustrated. Welbeck didn't play, Campbell didn't play," Wenger stressed.
