Who will end up leaving Arsenal first: Mesut Ozil or Unai Emery?It’s beginning to feel like the Emirates Stadium isn’t big enough for the both of them.Something similar happened at Manchester United last season with Jose Mourinho and Paul Pogba - and it was the Portuguese coach who ended up leaving Old Trafford.Several months before Mourinho was sacked by United, a video went viral on social media showing a frosty exchange between the two men in training.The footage, which appeared to show Pogba and his manager having a confrontation in front of the players and staff, attracted two million views inside one hour.

It proved that, as many people thought at the time, all wasn’t right behind the scenes between Mourinho and Pogba.

And now a very similar video has emerged from Arsenal’s latest training session which shows a frosty exchange between Ozil and Emery.

Ozil has been left out of Arsenal’s last four matchday squads after falling out of favour under the Spaniard, who is beginning to lose the faith of many Gunners.

Ozil, 31, took part in training on Wednesday ahead of Thursday night’s Europa League clash against Vitoria Guimaraes and Hayters managed to record the following footage…

There was certainly some sort of disagreement going on between the two men.

And Ozil set tongues wagging later in the evening by posting the following cryptic tweet…

It’s unclear who the ‘You’ in ‘You make me laugh…’ was about - although it’s fair to say that everyone assumes the World Cup winner is referring to Emery.

Ozil certainly knows how this would have been interpreted on social media.

It will be interesting to see whether or not Ozil is included in the squad for the Vitoria Guimaraes match - although it would hardly be a shock if he isn’t after what the German playmaker tweeted on Wednesday.

Unless results and performances improve quickly, the vast majority of Arsenal fans will be hoping that Emery leaves north London before Ozil does.
