I personally think it's too late for Graham Potter/Ralf Hasenhuttl because the attitude will be we need to win now and not gamble.
I don't think you have the team to play the football Enrique likes to play he's a purist. It will be like when Pep first joined city and I personally don't think United are willing to sell their young players to attract players he needs as city did.
Poch could be good In the long run I think you would get top 4 but everyone is playing catch up to City and to an extent Liverpool
