He'll hang on as long as possible & re-sign if no better offers come along.
Can't see any of the top 6 in the PL or title contenders from Germany, Spain or Italy coming in for him like.
This. He's on a massive wage and all he has to do is not be so shit that he relegates them. Being honest they should be more than capable of staying up and that's job done for him. Nice easy job where no one gets on his back if they never improve. Hell, even if he does take them down it won't massively harm his reputation, all the blame will be on Ashley as normal. He might leave, but he's got it pretty canny where he is it would need to be a big offer
