Honest question: Do you genuinely believe we have gotten no where since the Mourinho debacle? Because I look at the side that he left and the one we have currently and it's already a clear upgrade (and don't mention money because Jose spent a ton too). We also have done better than I think many expected in the league during Ole's time here. There's no doubt he needs to be sacked and clearly can't handle managing at the highest level tactically, but I have a lot more optimism in another manager being able to come in and have immediate success (a la Chelsea and Tuchel) than I did when Jose was fired.
The squad is as good as the manager manages to build a team out of it. We have bunch of individuals that might be better under the next manager, might not.
AWB, Maguire don't strike me as good options for a progressive high line, high press manager. There's 100+m of investment not really there. Pogba is on the way out and a possible problem as a character if he decides to stay on. We don't have a CF (have two in their deep 30's), midfield is in shambles and Bruno's form has dropped significantly.
We have Greenwood, Rashford, Sancho and one of them should be on the bench every game, whilst all of them are at their peak or need significant game time to develop.
Zero options at RB, bar AWB who is useless going forward.
Still have players on high wages like Martial(should be sold), Mata, Bailly, Jones or very much past it or waste of space (Matic, Grant).
And then there is Cristiano who doesn't fit that well high press.
With the benefit of hindsight I'd wait a bit to call this squad a great success compared to what Mourinho left. Whose midfield btw is still our first team option 450m later.
