Very much so. It's not like he's never had a good run before when he's had injuries. I would expect him to lose in the play offs (it is Sunderland after all), lose some players, sign some players, struggle to know what he wants to do and history repeats itself.
Ultimately I'm not fussed either way, that's just my prediction, he's gone thankfully. One thing I know is that looking at how our players can barely execute the most basic of football skills during a match day these days (and it's been getting progressively worse over the last few years to this point) I am delighted we will never have him, Holden and Macca "coaching" anyone at this football club again.
Sunderland can go up or stay down, we should feel lucky he's not our problem anymore.
