Manchester United's poor performance has been particularly prominent in the league and Champions League, and someone needs to be held accountable for it.
The team finished bottom of the Champions League group stage, much to the disappointment of Manchester United's management and fans.
The team finished in the top four of the league last season, spent more than £200 million to strengthen the squad, and expected to make a difference in the Champions League, but they did not even qualify for the group stage, which even Ten Hag himself did not expect.
However, as the head coach of the team, he must be the first person responsible for the team's defeat.
Manchester United are currently at a critical juncture in the buyover, and it is difficult to make a decision to change managers at this time.
The management appointed by the Glazer family has gradually withdrawn from Manchester United, while Ratcliffe's management has yet to formally take over the club.
Until Ratcliffe completes his bid for a 25% stake in Manchester United, Ten Hag's position should be relatively secure.
However, that security won't last long, with England** reporting that Manchester United will complete the full takeover by January.
Ten Hag doesn't have many chances ahead of him, and the team will face several strong opponents, whether it is Liverpool or West Ham United, who will put him under a lot of pressure.
Especially in the upcoming Double Red Club, another big 0-7 defeat will be the biggest test he faces.
In the list of options to succeed Ten Hag, the top of the list are Potter and Zidane, one is a top coach in the Champions League, the other has experience in coaching in the Premier League, and has some experience in building the team's squad.
However, both men will face very big challenges when they take over Manchester United.
What Manchester United needs most at the moment is not only the manager's ability, but more importantly, the ability to change the atmosphere in the team's dressing room and rediscover the spirit of Manchester United.
From that point of view, Mourinho could be the best option.
He has a wealth of coaching experience and can help the team rebuild their confidence and fighting power.
