An agreement we have with Desportivo Brasil; their lads come over and train with us a few times a season, and we have first option on them, I think.
Interestingly, I read that it stipulates in the agreement that any prices we pay for them are dependent on position, not ability/potential, which I thought was a bit odd.
They can't move until they're 18 from Brazil, and even then, they'd only get work permits for here if they've played for the national sides. We plan to send them off to FC Twente to gain EU citizenship with an agreement we signed with the Dutch team not so long ago.
