My question is - what right does FIFA or UEFA have to do that? How did UEFA secure exclusivity to European club competition? I'm still waiting for this answer
This, I don't get neither. I'd like to be informed on it however. Don't see how having a monopoly on creating a leagues obey to EU-laws neither.
As I understand it, the leagues are members of the UEFA and FIFA and the clubs are members of the leagues. This makes the players members of these world wide associations that organize the WC/EC/CA/etc. You are only allowed to partake if you are a member of this association.
Say I found a club and youbfound a club and we then organize a league for us. We have every right to do so but we are no part of UEFA/FIFA so we can't partake at UEFA or FIFA tournaments. So if a coach wanted to nominate you or me, it wouldn't be possible because we are no members.
Likewise you can organize a tournament and call it the 'SKILLS AND ROFLUTION (SAR) WC' and have every right to do so. The only thing making it less important is prestige.
