I don't think that Manchester United will retain Eric Ten Hag, there were some reports today linking Ipswich coach to the old Trafford job. It went further to say that Manchester United has already held a secret meeting with the man but nothing has been finalized yet, but they are hopeful that something will soon develop. With this I don't think Eric Ten Hag job is safe at Manchester United. I don't see Eric Ten Hag handling the affairs of Manchester United. The new management don't trust him enough, they are of the opinion that if Ten Hag was going to transform Manchester United that two years was enough to see that change, but so far Manchester United are far worst where Ten Hag meet them, so the decision to terminate his his contract. I'm sure the management of United will make known of Ten Hag fate soon.
The decision could go either way as Eric Ten Hag has not done well for Manchester United since taking over, especially as they finished the season very badly. With the team's performance under him being so poor, Manchester United will surely discuss his exit. It's not that Manchester United aren't negotiating with a quality manager, they're definitely looking for a quality manager if they get a quality manager and if everything goes well with that manager, they can certainly hire a new manager next season. If Manchester United trusts Eric Ten Hag without appointing a new manager, then of course he will give this manager strict conditions and if the manager accepts those strict conditions, he can stay at Manchester United.
If you look at Ten Hag's work with Man United in the past 2 seasons, it can be assumed that Man United has experienced a setback, and I think that reason is enough to get Ten Hag fired. This season Man United has been really bad, and even this is their lowest finish in the Premier League since 1989-90. If Man United continues to trust Ten Hag to handle Man United next season, that would clearly be a big question mark.
As far as I know, Man United has been interested in Thomas Tuchel, and it seems that Tuchel has also given a hint that he is also interested in becoming Man United's coach. But recently a new rumor has emerged, that after being fired by Chelsea, Mauricio Pochettino seems to be linked with Man United.
