I think this is just a matter of time and that Manchester United will come back to their glory days soon. Even with Arsenal, after Arsene Wenger left, it took them years and series of coach before finding their fit back. I’m so impressed by their performance this season and with all indications, it looks like they’re regaining their form back and this won’t go anytime soon. Manchester United inconsistency makes a lot to believe that Ten Hag is not the perfect coach for them, and that they need a replacement soon. I haven’t seen Ten Hag as a very bad coach, maybe he should be given room for more improvement, Manchester United could be better than this by next season if given the chance again.
Yes, I agree with you, Ten Hag needs a lot of time to make MU successful like the Ferguson era. I think in football, none of that is instant, At least it will take years for MU to be successful again and reach the peak of it all. But, even it's hard, the management should have collaborate with the coach to build the team by active to the market to buy potential player. And, I see this is the weakness, because I've seen it all this time, MU always lost and always unable to compete to get great players on the market.
