You’ve caught yourself in a catch 22 here. We’ve seen true individual brilliance shattering the system, overloading it and providing contingencies before the system can recover. We call such players game breakers, as does Pep. They are becoming fewer and farther between and it's not because football or its current systems are amazing, all-conquering entities, as we see routinely with Real Madrid, the last of the dying breed, routinely being kings of Europe.
Your bolded is a strawman you've just argued against with little input from me as I didn't say anything about Foden's ability, explosiveness or football IQ other than he is routinely lambasted for looking absolutely lost outside of a setup that has hand-reared him, which shouldn't happen to universal talent - it's called that for a reason. You've unironically repeated a part of my own post back to me with saying England need to conform for Foden to come to the fore. I've just stated that Foden has looked lost without the system and your counter is to provide a system.
These systems are not creating free-thinkers. Even the umbrella term for free-thinking is changing because we're wowed by players who look like they are capable of disinvolving from the system for periods of play before plugging back into the mainframe again. If football development was linear, we'd have all-conquering bots emerging left, right and centre who look exceptional within the remits of the system as well as fantastic without the system. That is not what's happening. One is in lieu of the other, for the most part, which is why the likes of Yamal are placed on a pedestal because so few around look like they can do what he is doing. As much as people seem to loathe it, clubs vis-à-vis nations will continue to prove the barometer and the subsequent nosedive in performance we see so often from players who look like beasts within an automated system to actually having to think and function in chaos or suboptimal setups will remain both the barometer and key talking point because this shouldn't happen if individual brilliance is running parallel with the harsh confines of systems that remove most of the thought burdens from players who are essentially on tracks.
Clubs and players are succeeding or failing because of the strength/weakness of the system - heroism by way of individual brilliance is waning; moments of unbridled brilliance to win games is fading; to the very end, some teams and players remain wedded to the strictures of the system to the very last pattern and kick of a ball to the point a player who dares to think outside the box at even more critical moments in a game will be chided, potentially subbed and might even see playing time reduced.
Of course that drives the bottom level up. It severely compromises the top end, however. Problem solvers, maestros and the type of player who doesn't need the system to be in his element are seeing their expression curtailed, and many of the lauded creative sparks of the past wouldn't get playing time now for their maverick ways or ability to take on the burden of being decisive factors in pressure situations. We'll see even less individualism as the youngsters being coached to absolute conformity to the system take centre stage. Automatisms likely to look better than ever, with expression and individual brilliance at their nadir. Or, in your idealistic view, a marriage between the two and hyper-bots with eclecticism the likes of which we've never seen will take the game by storm...
