I've watched most of their games this season. On the ball, in possession, they aren't actually that bad. Should have been a few goals up against Spurs. Played ok at Arsenal, but here is the big problem that they can't seem to fix. When the other team has the ball, they don't know what to do. How to press, close down passing lanes, track runners. It's a mess.
It reminds me of when you were at primary school and everyone is trying to score, but nobody is concentrating on the opposition going up the other end and scoring against you, so you end up with this really open game that just goes end to end. There's no control or game management. If the other team are clinical in their finishing you are toast. It's proper headless chicken stuff. Another worrying trend is that when the opposition scores first, they just down tools and give up. Like spoilt brats. No fight left in them.
I actually think that Ten Hag is a decent manager, but that job is wider than just coaching a football team, he's like a social worker/parent/head teacher/coach/chef/chief scout/media spokesperson...
Ralph Rangnick said all this and he was bang on the money.
