For much of the season, Mesut Ozil has been out of the fold at Arsenal. Unai Emery didn't seem to rate the German, and though he's come back into the squad over the last month or two, there's still time for the attacker to prove Emery right. 

With 4 games to go in the Premier League, Mesut Ozil could be entering into a key part of the season. So much is on the line for the Gunners, namely a top-four finish, and perhaps the German could have a big role to play.

If he plays well, that may go a long way to helping convince Emery that he's going to be important for the Gunners moving forward. A big assist or a few goals could do the job, and in that sense, there's enough time to prove his worth.

However, on the flip side, if Ozil isn't able to impact his team over the coming weeks - maybe that will serve as proof that he should be sold by the Gunners this summer. The reality is that he hadn't picked up a goal or an assist since February prior to the Gunners' loss against Crystal Palace - and that's not good enough. He hasn't backed up his increased involvement in April and March - so why should Emery waste more time? Sure, stats don't tell the whole story, but they give a good synopsis - and those that have seen Ozil play this term will attest to his mixed form.

He needs to do something in the coming weeks - or it'll be time for him to go, and Emery likely recognises that.

Arsenal fans - where do you stand? Is it time for Ozil to go? Let us know below!
