Giggs obviously can't be a serious long-term solution unless the United board are completely out to lunch. They have just witnessed a proven PL manager with 11 years of experience at a decent club (Everton) crumble under the job and fail miserably, so how could somebody in the right mind then give it to someone without ANY experience (unless you count 4 games as caretaker without any pressure)? It just makes zero sense. Following Ferguson and rebuilding the squad was always going to be a tough gig, but if a proven PL manager like Moyes and a very experienced manager like van Gaal falter like that, somebody like Giggs has no chance.
Appointing club legends as managers often goes horribly wrong. Just look at Milan, they tried this twice last year (first Seedorf, then Inzaghi) and both times the experiment failed miserably. It amazes me that big clubs like United and Real are even thinking about the possibility of giving the jobs to Giggs and Zidane without them going to manage a club somewhere else.
If United are as ambitious as I expect them to be, there are only two realistic options next season: Guardiola and Ancelotti. Trying to get Guardiola absolutely has to be a priority, especially because you don't want that guy to go to City instead. I think the project would interest Guardiola - history and tradition at the club, tough league, open cheque book. If Guardiola can't be convinced, personally I'd also be very happy with Ancelotti, who has proven that he is a very good and flexible manager. He's also publicly declared interest in managing United just a few days ago (

It's going to be interesting to see what happens until then. I believe United can only sign one of those two if they finish top 4, so form has to improve quickly and drastically. The last few weeks were supposed to be a relatively easy part of the schedule, yet they dropped a lot of points and if they continue their bad run, a top 4 finish is all but a sure thing. So, do you trust van Gaal to pick it up? Do you trust Giggs as caretaker? Do you think Ancelotti could be convinced to take over midseason despite him saying otherwise, and if so, do you do it if it kills your chance of getting Guardiola? Tough situation.
In a perfect world, SAF comes out of retirement, leads the club to another PL title and then Guardiola takes over next summer. Never going to happen, but hey, a frustrated fan can dream, right?
