It's a risk but as many have said, Ancelotti was not happening if his demands and what he's getting at Everton are true. Allegri might be fine with seasoned players with some italian players here and there. We have neither. He would have had Aubameyang and maybe Sokratis who can understand him. It would have been even worse than Emery levels of misunderstanding with the group.
Vieira to me is a no-go, he was terrible in the MLS, and is terrible with Nice. Absolute legend of a player, nowhere near as a coach at the moment.Henry is the same, disaster at Monaco, now lost in the MLS. Marcelino was not a sexy thought either, and has the same problem with communicating. I believe Mourinho wanted the Arsenal job and Sanlehi wanted him but it was just impossible to do. Even if he did well there's such a massive part of the fanbase that loathe him that, not if but when he left, it would also mean the door for Sanlehi.
We would need a stronger word than toxic for the atmosphere it would have created.
The top picks that are Naggelsman, Rose, Tuchel can't join now and look out of reach anyway. In the summer they will no-doubt have better offers squad-wise.
It leaves us with Arteta. If this season is a write-off let's get a chance to see what he can do, it will either be the same as keeping Ljungberg or an improvement.
Unless he gets us relegated
