“Mesut had a lot of other opportunities at the time because he would have been a free agent and could have commanded a £40m signing-on fee elsewhere. But he never wanted to leave.

Ozil has started Arsenal’s first two games since interim boss Freddie Ljungberg replaced the sacked Unai Emery at the end of November.
He is in contention to figure from the off on Monday night when the Gunners travel across London to take on city rivals West Ham.
Arsenal are 11th going into the showdown at the London Stadium, but will jump up to ninth if they beat the Hammers.
