He didn't make adjustments and didn't recruit the players needed so even though he recruited some players it didn't help Man United's squad become stronger and more solid. Erik Ten Hak should try to find the players needed not just recruit players because if he makes a mistake next season then his future at Man United will be very risky to be fired. The defense line should be the focus because Man United are so weak in that position when they play and it is easy for opponents to score a goal their goal.
Now Man United have overhauled the management and coaching staff and they have managed to bring in some players now. This season will be a gamble for Erik Ten Hak because the management has made many changes as he wanted. If it still fails then I can say Erik Ten Hak will not last until the end of the season.
Ten Hag made this effort last season, but many of Manchester United's main players suffered injuries, which prevented Ten Hag from making Manchester United's performance better.
Not only the defense line but almost all of the Manchester United squad lines need improvement and I think Ten Hg knows what he has to do and of course he is also aware that next season is his last chance.
If Management fully supports Ten Hag to spend a lot of money on the quality players that Ten Hag wants, I am quite sure that Ten Hag will be successful next season.
Last season the problem was only with the Manchester United squad which was not capable, not Ten hag strategy.
Yes, I quite agree with your sentiment bro, Eric ten hang has proven to me to be a reliable manager in the two seasons he has spent in the club, just that their are some things happening in the club that is out of his control which have affected the team negatively, and that made him look as if he doesn't knows what he is doing, but no, that isn't true, what really convince me that he is actually not the problem of Manchester united is that, upon all what Manchester united went through last season, he still manage to win a trophy, that shows that he is not just a manager, but also a winner, let's not forget that he won something the season before last, so I believe that if the hierarchy of Manchester united support him the more in terms of transfer, by giving him all the necessary support and players, he asked for, he will surely deliver, though expecting him to win the league will be too sudden and too high of a expectations, but he will surely get there, if he is given the necessary support to succeed as the manager of Manchester united.
