I don't think it will be a turning point, they won't really turn around until Moyes is able to step up to being a manager of a club that size which sadly I doubt he ever will. They deserve credit for turning it around last night but Olympiakos are shit for a team in the knock out stages, they should be able to beat them easily. I think this will only be a very temporary boost, a bad defeat to city next week will see the dark clouds return. And there are very very few matches when playing Giggs in the middle is going to be the solution to anything.
