This summer looks like it will be a busy one for the club as Unai Emery finally gets a chance to make his mark on the squad.

While most eyes will be on the players coming in, there are a host of players who are set for the door and we could see as many as 12 (not counting youth players) finally depart.

There were reports back in January that Arsenal had exercised their one-year extension option on Nacho’s contract but, at the time of writing, that still hasn’t been confirmed by anyone inside the cub.

He is out of contract in the summer and has been heavily linked with a return to Spain with both Barcelona and Real Sociedad said to want to add him to their ranks in the summer.
