Jose
Moyes
LVG
Rangnick
Ole
IMO, you would have been a dogshit team to watch under Mou but I think if he was supported appropriately you would have had relative success (though I don't think you would have won the league vs this City/ Liverpool), Moyes a little less so because I don't think he has a top managers mentality, LVG would have at least ensured you could control a football/ possession and maybe evolved over time, Ralf I think would have been better behind the scenes but I would prefer to support him financially than Ole after seeing what he did with the money provided.
You are entitled to your opinion but I do find it a bit odd that you have Mou first because of his success, and Ole last when he almost won the same european trophy and went out on penalty kicks against a much stronger Villarreal side than the young Ajax one that Mou bullied off the park.
LVG - Won silverware and laid foundations, had a clear vision of how he wanted to play but let down by poor signings, and his work undone by Woody appointing Mou. Also won a lot of the big games.
Jose - Won silverware albeit at a heavy cost, left us with an overpaid mess (Alexis broke our wage bill permanently)
Ole - Played the best football, almost won silverware, stayed too long
Moyes -Probably let down by the board but didn't help himself with his smugness since day 1, never had the dressing room, mostly just cross cross cross. Celebrated too wildly in the comeback against Fulham at home.
Rangnick - Did absolutely feck all. Tried to start with his 4222 philosophy and ended up having to rely on Fletcher and Phelan to bail him out.
