Arteta spoke about his willingness to get Mustafi tied down to a new deal in July.

"That’s something the club has to address but he knows my opinion,” said Arteta.

“I’m really happy with him as you can see. The way he’s playing, how committed he is with everything we’re trying to do, the level in his performance ever three or four days, he’s been really consistent.”

Unfortunately for Arteta, it appears he has failed in his attempts to keep the German at the club.

He might be disappointed, but the same definitely cannot be said by the Arsenal fans that have had to watch him for the last few years.
