Go and watch our first 2 games of the season again...or go and see how he got Ajax to play when they were at their very best in 2019 and then 2022.
Ten Hag tried to stick to his philosophy vs Brighton and Brentford, but the results and overall performances showed that he doesn't yet have the players available to do that. After those first 2 opening games, he changed things up...when we sign a technical GK and a new #8 for next season and see how we play then, you can come back to these posts of your claiming that he doesn't have a possession-based philosophy.
Also, pressing high and quick transitions are both features of most elite teams these days, even City and Arsenal, who are both possession-based as well.
