And the club has to consider if Zidane really can get the club out of the rut beyond this season, which I don't think he can do really...
United needs to start rebuilding the club from the ground up. There's no other way around it imho.
I don't think he can either, but I'd like to see him there even if it's just to prove me wrong. People put too much emphasis on managers making that much of a difference or expect them to come in and revolutionise the squad and win trophies immediately and that just never happens unless you have a world class squad to begin with. Managers like Pep and Zidane already inherited world class squads from world class clubs. I mean, who couldn't win a title with Bayern and Barca? Let's see them manage a mediocre Championship team and see if they can win them the Championship and then the Premier League within a few years. Then I'd call them a world class manager. At least Fergie started from scratch with United and built his team up to be great. People should start blaming the players more instead of using managers as a scapegoat (unless they're just tactically going to pot) but they rarely do. Sometimes teams just don't gel or have a bad run of forum and sacking the manager for a new one usually does very little to remedy that. United getting Zidane probably won't make any difference, especially this season.
