A little bit harsh imo, he started addressing some of the issues that we all could see and that side had half a fist at getting play-offs, before he left one bloody week before the season started (after the understanding that was afforded to him).
He has also done it before at clubs, moving for Steve Bruce, then starts complaining when he gets stick (often through his son, who he now employs). He had a chance to build something here, there was a big Ron type of feel and we (mainly) were behind him, in the end he is a snake and deserves to lie in the bed he has made.
