The fans want it, to bring Manchester United back to the Sir Alex Ferguson era but there has been no right replacement to revive the soul of the red devils, currently ten hag is not really working, at MU ten hag is only reuniting with his ajax players, 
he has no concept in building a team.I see after the Fergi era who can really talk a lot in the EPL is only Jose Mourinho, after that MU went downhill again until now. [...]
They really need new hands, i heard that Ten Haag will leave Manchester United in October, don't know whether this information can be validated or not, but that's the rumor i heard. If Ten Haag really leaves, there are 5 suitable manager candidates to replace him, Gareth Southgate, Thomas Tuchel, Kieran McKenna, van Nistelroy & Graham Potter. Which manager do you think fits Manchester United's style of play philosophically?
But unfortunately Man United's performance at the beginning of this season did not develop at all and the most painful thing was that they lost to their rivals with a crushing defeat without being able to score a single goal. So it can be said that Man United's management decision to continue to trust Ten Hag was proven wrong because until now there has been no change. Last season's inconsistency like that will continue if he still coaches Man United. So I think he should be fired for the good of Man United.
In my opinion, among the coaches who are suitable to replace Erik Ten Hag is Ruud Van Nistelrooy. Because he has the capacity to coach Man United to be better, he also has experience at the highest level when coaching PSV Eindhoven. In addition, he is also one of Man United's icons, of course he will easily adapt to the Man United environment and can bring Man United back to glory.
