I can see a continental manager doing very well at United, given the structure and stability they have in place at that club. Someone like Mourinho wouldn't be ideal for us, he would do even better than he is at Chelsea with such a good squad.
I would love them to appoint someone without experience in top games, like Moyes. Any UK manager would be ideal for us, because there isn't any quality ones out there. All their ex players are piss poor managers as well, best would be Solsjkaer for them.
Anyway, reliable united sources says that the new manager would be unveil in a matter of days, but firstly he must quit his his current club contract. David Gill also confirmed the new manager "will have experience in both England and European competitions" and is in favour of giving youth players chances. Tony Pulis did quite well in Europa league...
