This is a hard one for me. Although on paper there should be only one winner, I'm not a massive fan of Mourinho for a few reasons. Having said that, him coming to United will hopefully most likely guarantee trophies, whereas, due to the lack of experience from Giggs, our following seasons could pan out like it has under Moyes and Van Gaal. However, if we look at the aforementioned managers, they had/have bags of experience - the latter having expeirence in Europe too, yet it didn't seem to work.
Therefore, it begs the question. Do we need another experienced manager, who will come in and possibly chnage up quite a lot of things (staff, players, formation, tactics, etc) or do we need someone who's knows the club, knows how they work and knows the players? I can imagine all of the players will have massive respect for Giggs. SAF and Bobby Charlton are bigs fans, etc.
In an ideal world, if we could have Giggs as manager, but bring in a great coach - someone who is tactically brilliant, whilst Giggs sticks to just the actual 'manager' role, i.e, pep talks, choosing the team, player morale, etc, then I'd be all for Giggs being next manager. We'd also have to have a good scouting system. Bit tired of us paying excessive amounts for some players. It's not my money, but I think over the last couple of years we've been a bit careless with our spending.
