But the rules are the rules, Andries. Experience certainly helps, but then you could say South American referees are under far greater pressure than their European counterparts considering they could be murdered for their calls.
So actually, those who referee in Medellin or Rio would actually handle the pressure far better than those in London or Turin.
And it's a bit strange to use the "World Cup standard" argument against American referees when you complain about that standard every waking hour of your miserable life. That's rich, buddy.
