No-one knows. Wenger's frozen him out completely and no-one can understand why because he was performing very well for us. The only reasons I can think of are that Wenger wants him to be sold, they've fallen out or he's not working hard enough in training (possibly all three!) because there is no way in hell that Walcott should be getting into the team ahead of him.
Just when it looked like he was becoming an effective team player, Sanchez was fit again and he stopped playing - which I don't think is fair because his performances have been surpassed Sanchez's based on this season. I don't blame him if he leaves in the Summer, with the way he's been treated. Sometimes it seems like Wenger can pick players based on their names rather than their form. Ramsey also being a prime example. I'm hoping he just doesn't waltz his way back into the side when Elneny and Coquelin have complemented each other so well.
