The sad truth is, Wenger simply can't handle the English mindset. Not because he's a bad manager, because he's undoubtedly a world class manager. Not because the English mindset is bad, because it's amazingly effective. They just don't click, it's as simple as that.
And this is a warning sign for everyone who wants to radically change the way kids are coached, to mimic some other country's methods. If you tell a bunch of English kids to just play the way they like, it'd probably end in a brawl, or rugby if they're upper-class.
We tried the same shit in Hungary, we've long abandoned our traditional mentality that was based on vision and positional awareness and every five years or so, someone comes up with a brilliant idea about who to copy. Once it's the Dutch, then it's the Italians and so on. And it never works out, because that's not the way we think.
I've played with or against absolutely amateur footballers from Hungary, Spain, France, Ukraine, Australia and England and the way they approached the game was completely differently, and it has clearly nothing to do with coaching.
Of course, coaching methods have to evolve, but changing the philosophy leads to disaster.
