Looks like Mustafi's contract is being written off as well, which is another positive step towards leaning out the bloated middle of the defence, far too many bodies there (Gabriel, Holding, Chambers, Luiz, Mari, Socrates, Mustafi with Saliba and Mavropanos both out on loan, although I'd expect the latter to go from loaned to sold this summer) . Good news about one MO replacing another MO too!
Ozil was at his best when we had all the players to do a lot of intricate passes in the middle (Cazorla!) and the team were a lot less goal-shy. In the modern Arsenal side who shipped a ton of goals and had problems scoring them... no room for a luxury player who's tracking back and pressing was perpetually half-hearted and didn't do well with pressure.
