I like him as a guy and he got a great reception but they are even more fickle than anywhere else and they will turn on him if and when the going gets tough.
Tbf the majority of United fans were even behind Moyes to the end. You got a few flying aeroplanes with banners but they were still in the minority until very late on.
LVG and Mourinho the bigger names attracted far more criticism, but understandably as they both were given large amounts of cash.
Where they both went wrong was in trying to impose two different styles of football, both absolutely foreign to that with which United fans had grown up with and used to.
The possession style of LVG or the very structured and disciplined style of Jose with the emphasis on not conceding, wasn't at all welcoming and was always unlikely to bring much entertainment. They both won domestic cups but came nowhere near meaningful honours.
Solsjkaer has tried to give them the football style and given their crop of injuries and unable to change a less than ideal squad left behind, has for the most part exceeded any realistic expectations.
Doing extremely well over a three month period with a decent team if everyone is fit, but not so decent without Rashford and Martial, has been enough to secure him the post.
He is though absolutely unproven in other equally important aspects of the managers job, and part of a single season is just that, an extremely short time on which to base any long term decisions, and after three consecutive and relatively quick fire failures at appointing the right man, its one they had to get right.
I know the argument was he needed to be in now for Summer transfer business and stability, but to me it's too quick and a mistake.
Spurs are suffering now for not recruiting in two successive windows, the squad is nowhere near deep enough and consequently players have been overplayed, most didnt even have a summer break with the World Cup, they're paying for it now but Spurs' shortcomings only masks how well Pochettino has done over several years for me.
Spurs haven't won a major trophy since 1961, but United aren't Spurs and with cash and a better squad I'm convinced he would have been ideal even if far more difficult to secure.
Solskaer might work, but it's a huge gamble, he's never worked with a technical director or been involved in the perils of recruitment before, he hasn't much status or name and is totally reliant on the magnet that is the club's name. If he fails in reaching the top four then he may find it very tough indeed as United generally shop only for the most expensive goods, most top players want Champions League football and the name of Solskjaer won't hold much attraction.
They've acted too soon for me, he'll likely be gone within two years and possibly half that time.
