We could replace him with Glasner. He's a "mid table guy" who can actually coach a team and guess what! He won a trophy too, against much harder teams than Ange had to beat, and he also won the Europa League at Frankfurt too if that helps? Just all round more successful than Ange under much harder circumstances.
Everyone's happy - rid of the fraud, in with a proper coach.
Ok, what about Glasner then? He's won the Europa league and FA cup in the last few seasons and overcame much, much harder circumstances to secure a decent finish in the table for Palace. He's proven he can fight on multiple fronts AND succeed. Would that be a high enough bar for you?
Glasner is about to extend his contract.
But for argument sake, that is getting closer to the type of profile you would need to stand a chance.
IMO Glasner isn’t worth the risk. Hes won EL but so have we now. Why take a gamble on a sideways step?
