I recently saw a video of Xavi explaining his tactics at Al Sadd. The way he talked about that he loves possession made me think of the difference between LVG and ETH. They both really like possession, but LVG loves possession and ETH likes possession. While LVG does get angry with his players when the ball doesn't move up fast enough, with ETH (almost) every pass needs a purpose. You can pass backwards, but if it's not to cool down or something, it's just a pass for passing sake. I think that's the difference between ETH and other Dutch coaches. Frank de Boer and Schreuder are probably most obvious comparisons, where they'll use practically the same squads, but they've lost all their grit. It can work, like Schreuder versus Rangers, or Frank de Boer with his consecutive championships, but hot dang it's boring and so far it looks like it won't get you anywhere at the higher levels of football. So, LVG can complain about the pace all he wants, but if he views dominance as a ball possession number, then his strategy will reflect ball retention over dominance moving forward anytime.
If not losing the ball is more important than moving up front, the fear to lose the ball will be too dang high.
ETH loves Dutch football, but I think for him it's more about dominance in its broadest sense and creativity, and not about 70% possession. I think he'd rather emulate Simeone's peak with 30% possession but still feeling unbeatable, and every move forward is a very good one, than he would 80% FDB Ajax but all the legs are shaking. Thank god his baseline isn't Simeone's baseline, though, and in my opinion that offers a much more resilient side, too, since he's never too afraid to attack, while taking all the aspects of the game very, very seriously.
TLDR: 58% possession ETH > 62% LVG any day.
