The game is producing system players. Superstars are becoming a rarity, because the Guardiolas of the world have no need for new Ronaldinhos.
It's not Pep's fault. It's everyone who is trying to copy Pep are too blame. You can also argue the German gegenpress is also plays a part in the system players. But no one really wants to have that conversation. Collective over Individualism. What about Jose he also plays a certain part in this.
There is no subtly to most of these new coaches. Pep is like a season ahead of everyone else. Just when they catch up hes already changed to something else. Pep was taught by Cruyff who in turn got it from Vic Buckingham and Michels. He's kept Total Football alive and evolved it.
Sports are all about copycating one another withim their designated sport. This is not that much different from when people blame the Warriors for modern basketball. Teams tried to copy them but still didn't have the ball movement element to their game that the Warriors had and it didnt look the same. But all people want to blame is OMG they are shooting 3's.
You can actual blame Rijkaard for Ronaldinho and the players whove come after like Hazard and Neymar. Who was the one who moved Ronaldinho from #10 role to the LW because of being a defensive liability and Barca kept on being hit on the break.
