Don't think Emery has the final pieces of the puzzle to do it at a top club. Lacks the charisma and poise needed. Yes he did alright at big clubs before, but also those tenures imploded when conflicts happened. Arteta barely scrapes by himself, success will help him.
Klopp was the other way round, so much charisma people didn't mind the times his squads fell short cycling off the dope.
Slot has looked out of his depth since the moment he had any setbacks or bad luck whatsoever. Last season was a bigger fluke for Liverpool than Leicester with Ranieri.
Was saying this the other week, but if Iraola goes to Palace as has been rumoured, he might be hoping the Arsenal job eventually falls in his lap. He'd be a decent successor in the sense he'd understand what Arteta's been doing without giving it all too much respect.
