I've read this forum for 10+ years, but never posted before. Not sure if this is quite the right thread, but thought i'd chuck my thoughts out there.
Firstly, let me preface this by saying I don't think Ole is a good enough manager to lead us to trophies, he doesn't coach a pattern of attacking play, that sort of thing; but right now I can't see anyone who's an obvious, gettable replacement.
But, even if we did replace him, do we think many other managers are going to do a better job with this squad? Whilst, on paper, there's plenty of good players in the squad, I think it's fundamentally flawed. It lack's cohesion, an obvious philosophy (I think this is structural, rather than be something you can pin on Ole), and carries far to many players who trade on reputations rather than what they produce on the pitch - Pogba, Maguire, Martial, etc - But this statement leads me onto my major point.
Ronaldo.
Not watched loads of him in last few years, I was aware he'd lost his pace, and was purely a finisher these days, but i've been astonished how little he's offered in almost every game. He's rarely in the game, his touch is heavy, and when does have a chance he isn't always this lethal finisher we thought we were getting - See him running offside from the Rashford ball today. You can't carry passengers in modern football and I think we're stuck with him for the foreseeable.
We also lack a midfield engine room of any sort. How we didn't reinforce there this summer is beyond me. If that's Ole's fault then he needs to go for that alone.
We can replace Ole with someone new, but how anyone else is going to shape this mishmash into a title challenging team is beyond me. We can replace Ole, but I don't think it's going to take us anywhere fast unless the changes are farer reaching than just replacing him.
