Ten hag is not seriously fixing their problem last season. He doesn't strengthen their midfield. That's the main cause of their loss to Liverpool. They are too open in midfield. It lets opponents exploit their mid easily. Also, the loopholes in their midfield make them couldn’t mark anyone for the entire game.
It's clear to see that they lost by a huge margin at home to Liverpool.
He doesn’t seem like a coach that can even identify his team’s problems not to talk of solving them, he had the whole transfer window to identify and strengthen his team’s weaknesses but chose to sign players randomly. A lot of players are not performing well but he doesn’t even seem to know about it and still choose to play them weeks in weeks out and these are important roles that when not strengthened the team will keep struggling. Casemiro clearly is not good enough to be United’s Defensive Midfielder but still chose to use him against Liverpool, Urgate should help fill that space when he joins up with the squad but there are still lots of positions that’s needs to be improved but then it wouldn’t guarantee that Ten Hag will be able to manage the team to their best.
Liverpool was clearly the better side and they deserved the win.
