I think we've been in a bit of a tactical lull in the PL since the beginning of the Guardiola era, the sweeping success of his team has spawned an obsession of "control" amongst premier league managers, I think match load certainly plays a part in that and I think Guardiola's own system has changed a lot from the days of his swashbuckling, all-conquering Barcelona side that flourished with the individual genius of the likes of Messi, David Villa, Iniesta et al. His City team have been far more system-obsessed, players like Haaland are now the "jewel" in the team, a player I think he would have considered far too rigid and unrefined to head up his Barcelona team, but now his sheer physicality and flat track bully dominance in the scoring charts is exactly what a Pep system needs.
This season has been a very refreshing and interesting change in the status quo IMO, teams like Forest and Bournemouth are thriving without the same obsessiveness over in-match control. The problem with any system is when it's around long enough, the blueprint beomes more and more defined on how to counter it, and we've seen weird topsy-turvy years in the league like this in the past when there's been a big tactical shift in the game. I think we're watching Guardiola's last season at City anyway tbh, and once he's gone I think we could have a few turbulent years whilst the new "meta" of the league establishes itself.
