Arsenal are more pragmatic than City, they showed a few times that they don’t mind having less possession even at home.
For example, it’s how they dismantled Bayern (a quality side) earlier in the season. I think at one point in the first half they had less than 40%. You could say Bayern forced them to, but from what I saw, it was a deliberate plan by Arsenal on that specific day.
Though of course that they’re more aggressive off the ball than some of the lower teams who sit back more, that gives you some opportunities to play in behind and also grab parts of the game by keeping the ball (which we had to do against them recently and did).
More generally speaking now, when a team that wants to control games by a lot of possession isn’t in it’s best form, sometimes a poorer version of that yeah, looks slow and boring. Such teams, when they struggle breaking teams down, will not suddenly begin to play wildly. I understand that’s what some fans would do, but it’s not a FIFA game where you press fast running all the time and play direct long balls to wingers.
There can be a fine line from circling around in order to break but struggling to and succeeding and looking like one of the most exciting sides in the world. I’m not saying it’s us by the way, because ever since pre-season it looked to me like we struggled in pressing from the front, defensive transition and set-pieces.
Spain under Enrique got a lot of critism for doing too much possession without enough verticality. I heard things like that football is finished, etc. Of course it’s not. A lot of the same principles are now at PSG. You also need players (which Spain eventually got with Yamal and Williams, but through the centre they don’t have a real recognized striker, often playing with a or double false #9’s).
You have to play together on and off the ball, accuracy and quality comes first before speed. Once you get that right, then you can go faster. I don’t mind playing slower, but then you have to accelerate and vice versa. Switch sides, penetrate, if you can’t, go back in order to go forward again. Even the best sides in football don’t play only vertical and 200mp/h all the time. There is fundamentally nothing wrong with Slot’s theoretical idea how he’d like a top side to play. Putting it in place and consistently providing results is another thing.
Then different taste among fans is something else.
