Well, the caveat here is that supporters often think they want a possession-heavy style of play, but then moan when we implement one.
I remember the jibes thrown AVB's way for prioritising possession - I don't think I've ever seen more use of the word 'sterile', outside of a laboratory. Same for late-stage Poch, when people would bemoan our tippy-tappy, sideways passing.
The early and peak Poch sides did *not* rely on possession. They could certainly use it to their advantage, but the biggest strength those sides had was their absolutely monstrous press, which absolutely smothered teams in an era before everyone adapted to high pressing.
In this style, passing for passing's sake wasn't really a thing. In many cases, passing it around was done with the hope that we would lose it, because then we could counterpress and hopefully win it in a high area with the opposition out of position.
So, folks need to be clear on what they want, too - it's easy to say Frank should prioritise more possession, without understanding what that means, and how much that goes against what even our greatest manager since Bill Nick (imo) wanted to do tactically.
I'll be clear on my part.
Yes, we did use young aggressive pressing, but we also had
a lot of possession in games and (critically) players who could both play a passing game too.
The high-press was a key in those early days, yet once we got the ball we kept it and used it. Very similar to Emirates Marketing Project in their prime.
What I want is something akin to peak-Poch-meets-later-Poch. Which is absolutely possession football along with an aggressive press. Ironically, the reason we did not manage to ever win the league under him is precisely because he could never break down the 'smaller' sides, who would sit deep and exploit that part of our game/challenge us to pick the lock; Eriksen could sometimes.
Sir Bill? He (like Arthur Rowe) wanted fast, fluid quick touch football built through midfield. Now, you can say that isn't necessarily 'keeping the ball', but it is possessing it and using the bloody thing to entertain, to attack, to score goals and try to win football. So in THAT sense it is possession football. It is not dissimilar at all to what Poch wanted, and did.
Poch's average possession stats were 57% with us (average stats generated by some ai thing).
Postecoglu's possession average was 60-62% (average stats generated by some ai thing).
Frank with Brentford in the Prem was approximately 41 to 48% possession (average stats generated by some ai thing). With us it is currently 53%.
We are currently averaging 9.5 shots per game, our lowest in the Prem since 2003/04.
There are doubtless more of these things to be found and used whichever way anyone wants (context is crucial for sure)...
