My language said they are better off the ball. You're overthinking it, and yet to answer whether I'm wrong or not.
You'd literally have to sit down and ask ten Hag why he started. What we see in games is just a little snippet. We don't see what's going on behind the scene and how the players perform in training. I mean, Van de Beek was a success under ten Hag at Ajax and even he didn't start, so I don't know. However, as I said, the midfield trio were able to dominate the ball for the entiret of pre season and even the game yesterday, so I'm not sure how you can say he's not a posssion manager.
The problem yesterday wasn't that we couldn't keep the ball, but our build up phase was way too slow, thus inviting the press. This was where Fred was massively at fault. As the "connector", he has the most important job in the team. Started well, but as soon as he gave away the ball, his performance started to deteriorated. This is why ten Hag has priroitised De Jong or someone of that ilk during the summer, and we saw the difference when Eriksen dropped deep.
Would you class Van Gaal as a ''Cruyffian disciple"? If so, fancy explaining to me why he played Fellaini and Herrera in the midfield who, lets be honest, are no better than Fred and McTominay on the ball? Whilst you're at it, can you also explain why we were able to dominate possession? Don't quote me on this, but I'm sure when Van Gaal was here, we were at the top of the possession stats. Even went to Anfield and bossed it! Having said that, we had Carrick or Blind in the single pivot, and that is the importance of having someone who can dicate the game in hat positon. Unfortunately, Fred is not really that player and until we get that player like City have Rodri and Liverpool have Fabinho or Thiago, we will struggle with our phase play. Teams will press us because they know they have a chance of nicking it off us. You do that to City and they'll just pop it past you, hence why teams don't play the full press. That said, I know it's Brighton, but we won't come up against a team as well drilled both on and off the ball every week. Potter deserves a massive amount of credit. Before the game started yesterday, it showed their away record vs the top 6, with them only losing to us and City.
I think when it comes to the final third, we'll always score goals. Team certainly won't look at us with fear like they used to, and it's clear we need more experienced bodies in the front positions, but I think we'll always score goals. Despite only scoring one yesterday, we could have had 3 or 4 on another day. Rashford with his two chances and Bruno's one early on.
