Pep got fast tracked into coaching based on his connection with Barcelona, same with Arteta at Woolwich.
I don't know if there are coaches as good of them around the world, but they certainly have been more privileged than most who just don't have the same opportunities as they did.
I’ve no doubt there are some hidden undiscovered gems out there (maybe Ange was one) but it’s the idea that the coaching calibre/competition is, on average, the same in the A League or Japan as it is here that I find nonsensical.
Even in England, the coaching level has recently seen a huge rise due to the amount of top foreign talent being attracted here. The top coaches cherry picked. Of course that leads to a higher level of competition…
