I think one of the issues here, is the nature of the forum, and what people may expect from it (the forum). It's a public platform, and people are different and express and state their views in ways which should suit them... I for one thinks that's a healthy thing.
People (like me) who do not buy into the style of football, how the club is being managed, and the management style of Jose Mourinho, and how this fits with the Manchester United 'model' (style of play, bringing through young players, improving players, and supporting players publicly..) are going to need a lot to be pursuaded on, before showing a sense of gratitutude to Jose Mourinho. What about the players? I, personally, do think that a culture and tradition of a club, are more important than any manager, and what he thinks about how a club plays.
This is a manager that has played some of the dullest football I can remember at United.
This is a guy that has regularly rebuked, publicly, his players.
This is a guy who told Man United, that getting knocked out of the CL was 'normal'.
He has disrupted the squad, and when it suits, has absolutely no problem, not even a second-thought in blaming the players for how the team plays and performs.
It is only about him when things go well, as he takes credit, absolutely bathes in the glory and is full of explanations when we play well, and then tears into the team when they do not perform? What sort of manager is that? Man Utd fans are happy with that? If so, that's quite incredible, and rather sad.
So, no, as much as I like the defensive side of things (which isn't amazingly better than others.. look at how many goals Spurs have conceded for example..), I don't thinking gushing Mourinho with thanks and praise is what I am prepared to do. The biggest club in the world 'securing a top four spot' is no means for celebration, and this is the mentality that has crept into the club under Mourinho.
That squad should make top four, easily.
My respect goes to people like Hodgson, Benitez, and Sean Dyche, Pep.. I would extend that to Klopp too following reaching the CL.
This isn't moaning, or being miserable, it's a point of view. I love United, but Mourinho is no great flaming saviour of the team, and I am not sure how much more he can get out of that squad.
