Don't you think you are too harsh on Thomas Tuchel? What are the parameters you are using to measure a successful coach? The German won UEFA Champions League, UEFA Super and FIFA Club World Cup with Chelsea and the club was sixth in the EPL when he was sacked. In Bayern Munich, he won the Bundesliga and helped the club to qualify for the UCL in the next season after finishing second.
Jose Mourinho shouldn't be the best option because he once coached Manchester United and things didn't go well. The Special One has a good history of winning trophies, but if you want to consider the recent quality of both coaches, Tuchel will be my best bet.
Yes, the most suitable person at the moment is said to be Thomas Tuchel. The 51-year-old coach's class is beyond dispute, At the same time, he also has extensive experience at big clubs, from Dortmund, and PSG to Chelsea and Bayern. Tuchel's advantage over other candidates is that he is idle. Since leaving Bayern, the German coach has been unemployed, waiting for a serious invitation. I believe the MU Restoration Project might interest him.
In my personal opinion, I want former Barcelona coach Xavi to succeed Ten Hag. What do you think about this idea? As one of Pep Guardiola's outstanding students, Xavi also showed that he is suitable for the job of developing projects and young talents of MU - something he wants to do.
Xavi is a good coach and a very young one, I will concur that he can improve the club with his professional skills. However, Manchester management should move fast and look for a better coach before the season ends so that there will be no excuse that there is no good coach available better than Ten Hag because that will be a silly excuse.
The Premier League is not an easy league to deal with. Xavi did well at Barcelona because he already knew Barcelona and La Liga well. But if he went to Manchester United, he would face many difficulties. It is true that with the financial conditions that Manchester United has, Xavi could at least finish in one of the positions that allows access to the European Champions League and could even win the league if he stayed for a few years. But if they signed Tuchel for the long term, I believe he could create a team with a great chance of winning the Premier League. Even Mourinho, if he were signed for a long term, something like 5 years, could create a team capable of winning the Premier League.
