'He can decide the game by himself'

Ozil's work rate has been frequently criticised since he hoined Arsenal from Real Madrid for £42.5m in 2013.

However, according former teammate Tomas Rosicky, this criticism is unfair.

"I know Mesut very well. I played a lot of games with him. If you always see his stats, he is not the one who is not working," he said.

"Obviously what the people maybe lack with him, mainly in England, is that he is not the one who is going into the tackles or something like that.

"But if you see it in general – he is working hard. You can see his stats, what he has every game.

"Obviously I don't know about this season [as I am not playing or training with him], but that's what he used to be like and he was a hard worker – even in training. I know him.

"You have to see things in perspective, he is someone who can decide the game by himself."

"It can be tricky at the start for him, but again we will see his development in the new team.

"I think he will still be a key player for Arsenal and, if he is playing well, Arsenal will be playing well."
