Either way World Class is just a term and it doesn't really matter wether they even play for their national team or not in my opinion. A good point was raised earlier in the thread about players from lesser footballing nations playing for their country. It doesn't make them World Class by just being picked first for their country.
It's a word thrown about way too often imo.
Nope, I've not said that starting for your national side makes you world class.
The best players, from any country will make the national side, then of those international players some are better then others ect ect
Johnson (Sheffield Wednesday) makes his national side. He's not as good as Ronaldo. You're not automatically a world class player for getting in to your national side. You're world class when you're considered the best player in the world in that position.
If you're one of the best players in the world in that postition, why would other people be taking your national team place?
