For me, the MU has always been a team that will always be great, they need to do things better, and I think that the club's biggest mistake has been Ten Hag, I will always say that, because he is a coach who only does what he Says and everything in its own way and in that way you cannot build a team, it has to be with more freedoms, for now they have won the FA Cup , it is Something that I congratulate them, but for the MU to win, they need a change of caoch and urgently, One chaos is the FA Cup, another is the PL and at least they get to a place where they play the UCL.
Do not draw conclusions based on what you read on social networks. Here are some facts
ETH has won two silverware. Only Mourinho won more trophies after Sir Alex's retirement.
3 finals and 2 wins
He got the FA title through (never stronger) Liverpool and M. City
He won more trophies in 2 years than Arteta in 6 years in the strongest Arsenal of the last 20 years.
He is currently the second most-trophied coach in the PL, right behind Pep's
In PL this season, 45+ injuries. Almost the whole season without the most important players in defence.
He has a better winning percentage than Arteta or Klopp in the first two years.
Although everything looked bad the whole season, it is still better than Chelsea, Newcastle, Tottenham
In essence, his biggest disadvantage was the absence of Lisandro and Casemiro (and Rashford out of form), 3 key players from last season. Serious lack of quality players, but at least he formed a few new kids.
No doubt, Ten Hag has performed better than most of the Premier League coaches, but based on the expectations of Manchester United management and fans, they want something more like staying on top of the Premier League table and qualifying for the Champions League matches. The management and fans are not considerate of how he does it, whether he needs new signings or the key players are injured, what they want is a good result, they don't care to know how good Ten Hag has performed in the past, what they care about is to presently be among the top contestants of the PL.
Since Ten Hag couldn't provide such, sacking him and bringing another coach, that's what's on their mind. It's better to have it done than still keeping Ten Hag as Manchester United's coach
