Don't forget the time when they didn't have Ten Hag in the team Manchester United had many problems and they didn't have a good station in the Premier League at all but Ten Hag helped them to get improve and have better performance. However, he was not successful enough compared to many other teams but I think Ten Hag is a good coach for Manchester United and he was just not lucky enough to have a better place in the league.
First of all, I do not think he was unlucky. I also do not think he is necessarily a bad coach. For some reason, the decisions that Ten Hag has taken did not work out at all. At the same time, the players that he had brought in also did not perform well enough. A lot of people are of course angry at Ten Hag that he brought in Antony for 95 million and he did not do anything in the whole season.
Mainoo is so innocent and pure. I won't exaggerate, MU spent a lot of money and brought in a series of famous stars to finish 8th on the Premier League rankings. MU was eliminated from the Champions League group stage and the fourth round of the League Cup. Ten Hag led Man Utd in 114 matches, including 34 losses, 17 draws, and 66 wins, with a win rate of 57.89%. This number is not too different from the team's two most recent official coaches, Ole Gunnar Solskjaer (54.17%) and Jose Mourinho (58.33%). But anyway, he will have more time to build and lead MU towards success. Let's wait and see if Ten Hag is a good coach or just trying to pretend he is good.
If ETH is actually able to improve the situation of Manchester United I will actually admit that he is a good coach and we just did not give him enough time. But so far, especially looking at the season that just ended, it does not look like things are going to improve a lot in the next season. if he is able to bring in good results and also able to make the players like 95 million's Antony who are not performing well right now, somehow perform well and bring in better results from them as well, I think most of the people who are hating on him are going to admit that he is actually a good coach and he was just unlucky.
