Manchester United's problem is not just the coach, it's a problem that started in 2004 when the Glazers family bought Manchester United, the team started to slowly fall apart. At that time it wasn't very visible because they had a good coach, Sir Alex Ferguson, who had been at Manchester United since 1986, so the Glazers family didn't fire him, which is why Manchester United didn't sink. But after 2013 when Alex Ferguson left Manchester United.
it started to become visible that the club's owners were not prepared to manage the club and everything got worse because instead of selling the entire club, they only sold 27.7% to Sir Jim Ratcliffe and in practice the Glazers family is still in charge. Now Manchester United has 2 owners (Glazers and Sir Jim Ratcliffe), has 3 coaches ( Erik ten Hag Manager, René Hake Assistant Manager and Ruud van Nistelrooy Assistant Manager ), the whole club is at a very ridiculous. As long as Manchester United have these owners, they will not succeed. Unfortunately
