On the fence for me, for the reasons that
@axman2526 eloquently explained. It doesn't matter who is in the dugout as long as Winstanley and Stewart are still here. Nearly 4 years in and they are yet to make a single positive transfer contribution, other than bringing in Joe Shields and outbidding for blindingly obvious targets. There is no strategy for the squad and Cobham is being left to rot as well, everything is scarily like Bartomeu's running of Barcelona.
On Maresca himself - I think he has the potential to be a good coach but I am outright concerned he doesn't have the humility to want to change. He knows the problems in the squad, he knows the football is slow and stagnant but I think he genuinely believes he is right and everyone else is wrong. It's now to the extent he blames
everything - the players, the squad building, the niche roles of players, the refs, the red cards, the weather - but himself for a malaise. He carries on like Conte or Mourinho when it all goes wrong, without the history of success to show for it, and I think managers like that are outdated and outclassed in the modern game.
