How come that it doesn't work anymore, because you think that no one else is doing it atm? I strongly disagree that you can only play one type of football successfully. United just don't execute it well enough, too many holes, too many mistakes individually as collectively. Last season i don't think that most goals came from just luck, why hire a good tactician if it's just luck in the end.
Mourinho should have bought better and we need points in the league, otherwise for me there's still enough time to recover properly, a sacking at this point would be ridicolous, Woodward's not going to do it, imo.
