Manchester United’s defense has been so poor since last season, I was thinking things will change this season, but as we can see, I can’t see any difference. Three matches played, and they lose two games, even their first win was just luck for them, it will have ended as a draw. Manchester United's poor defense made their goalkeeper make lots of errors last season, they made the goalkeeper look so foolish. Right now, the only thing I know Manchester United can do is just to sack their coach. I don’t really think he has anything to offer, but if they can keep him, they will end up causing more damage to the team.
If you fully analyse the team you'll see that the defense alone is not to blame. If you watch their game against Liverpool you'll see that De Ligt and Martinez played well before the first goal. The problem of defence for Manchester United starts from the midfield. The midfield cannot control the game, they cannot press and win back balls and they give the ball away very cheaply. When you play that way against a good team you will be punished.
Look at the way Casemiro is easily dispossessed in games. This is the player that is supposed to win back balls. Same with Mainoo. The players who are supposed to win back balls and control the game are players who easily lose the ball and don't know how to keep the ball.
Then you have Fenandes who doesn't also know how to keep the ball. He's an attacking-minded player who just believes in putting one-time crosses, long passes or shots. With the kind of midfield and attack Manchester United has, this pattern of play won't work.
Ten Hag is using players who can't play a particular pattern of football and forcing them to play that way because that is the only pattern he knows how to play. The players in United as not as bad as people think. Under the right system, they will play much better. Ten Hag is a very arrogant person who can't even see that the way he plays is wrong. He never accepts that he is to blame and that is why Manchester United will be in this situation for a long time as long as he's their coach.
