Ok wait... What exactly is a 'classic manager'? The kind of manager who'll get established players in? With how crazy the transfer market since the oilers money came in the world of football, good luck with that. That would mean it's going to be a bigger gamble to splash the cash and it flops. It would be better to get an Arteta type of manager or even somebody like Poch to rebuild the club.
But yeah... I don't think the more proven managers will not touch United. They could try a guy who won't care if he fails tho, like Ancolleti?
Man it wouldn't change anything; they're still splashing heavily on players with these modern managers and it's not working, why not try the classic ones like Conte, Ancelotti and co instead? After all they're not into U21 project like Chelsea.
Yeah, Ancelotti would be a better choice imho, as I like the fact that he has managed Real Madrid which is as I've heard, the most difficult club to manage because the demands are high.
He won them the La Liga and the CL. Pretty sure rebuilding Man United would be a tad bit easier than the things he went through at Real Madrid.
