Many good points. For me, we have slowly been moving away from the 'tiki-taka' football that served us so well and towards a more open style. It makes games more open and creates more chances (unfortunately at both ends), but I'm just not convinced that the change sits well with Guardiola's principles. He cannot control the team if the team cannot control the ball. We end up doing more running, creating tiredness and injuries, and that then renders his small squad preference obsolete. For me, he needs to forget about trying to win with a different style and to return to his principles. That means better players but also better players who are fit for purpose.
Not that long ago, we could field a team where 7-9 players just did not give the ball away, and that then covered for players like de Bruyne, Foden, and Haaland. Nowadays, however, we might field only 2-3 players who can continually retain possession and the rest are much less reliable. The next signings will likely chart the direction of travel, but I know which way I'd like us to be headed.
