In real life, is there some kind of special system specifically for football or something?
I've always been curious about this. Eg. I work for a software company, and we've plenty of programmers working for us from outside Europe. I don't know the details I'm fairly sure they didn't have to undergo a programming test to prove they were good enough for a work permit - if the company wants to hire them then that's proof enough. I'd have thought it should be the same for a footballer or any other career.
