The performance from manchester united never improved since ferguon had left from the club. The reason I believe Mourinho was the best choice as a coach for MU is because of his immense impact on the team's performance, leading them to come close to winning the EPL and securing the Europa League trophy.
I think that the better thing for manchester united to resigned jose again. Jose has proven that if he is still being so useful for asroma even he is old enough now. I think that manchester united needs to consider signing a new coach.
This will give more benefit for manchester united at this moment compared to the defending ten hag to help club leave from its bad performance.
I think that ten hag will give no solution for this.
There are many things that must be improved within Manchester United to return to its glory days like the Ferguson era, one of which is appointing the right coach. The composition of players that Ten Hag currently has is very good for competing in the EPL and UCL, it's just that the potential that the players have is not shown optimally on the field, many say that Ten Hag has to change its strategy and approach with players, maybe that's the case. This will make the team performance better.
After the Ferguson era, Manchester United was no longer respected as a dominant club in the EPL, it was proven that The Red Devils had never won the Premier League title again. Maybe there is also some truth in what Jose Mourinho said in the past about United situation behind the scenes, and Pep Guardiola also said that they are not on the same page in terms of their vision and mission. Finally, it is possible that Ten Hag will also be fired or resign as United manager, if the team performance is unstable throughout the season.
