Ten Hag definitely wants to evolve us to a possession based team. The word possession is deceiving though, he wants us to be more controlling in games, not have possession for the sake of it.
Possession based teams generally are the best counter pressing teams too, you cant be one without the other.
There are many reasons why we are not looking like a proper possession team yet.
1. We have a game every few days, Ten Hag cannot work much on the training ground
2. We dont have the players in all positions, AWB, McTominay, Wout cannot play that, we need better players in those positions.
3. Our misfiring attack, we are struggling for goals so when we get a goal we seem to then stop playing and protect.
I feel over time, it will come.
