If he does stay it's likely Ozil and Sanchez will leave.
We will also be out of the CL, and we will be way behind spurs, Man U and Liverpool.
He isn't going to buy any world class players, let alone replace Ozil and Sanchez and we are going to be scrapping with Everton and Southampton for a top six place.
Anyone who thinks he can get us back challenging for the PL title or even a CL place, hasn't been paying attention.
If we get beaten at home by Man City, which is quite likely, then lost the following home game against West Ham, his position would be untenable.
Losing the next two games isn't that unlikely and, if we did, and he still wanted to stay another season, it would prove that he really has lost it.
He would drag us down further than we have ever been in the PL.
