Not sure where you work but you don't just come out and slag off a) Your team b) Your manager in public. Neither tactic leads to success. We don't know what is going on behind the scenes, we can only imagine. The only facts we know are that since he started the club has invested massive amounts of money. Do we have a stronger squad than last year when we came 3rd? Yes. Has the start to the season been diabolical? Yes. The performances have been rubbish and you can't blame the owners for that. So if this level of performances continue for a few more weeks then he deserves to be sacked for that, not for any other reason.
And then we should go back to loving him for being a United legend.
I am not saying come out and say the players and board are shit. There is ways of putting pressure on the board in various ways.
See this is the problem, invest heavily. Last summer he got a CB, RB, championship RW. We let go a ST, LW, CM and didnt replace them.
We reacted in Jan when we realised we are in trouble, so signed a CAM which we should have signed in the summer.
Also, I feel Ole is lost as a manager, he is completely blinded by some players such as Maguire, Rashford, Pogba.
I will always love him as a United legend and even as manager, it isnt his fault he isn't good enough. I do not blame him, none of us would give up our dream job getting paid £6m a year. Especially, when you have the self belief that you can turn it around.
It is the owners decision to decide whether he is the right man or not.
