ah so what does that mean exactly pls? it says 'again' so is this just precluding someone from playing in two 17s WC's?
"Again in another U17" says to me they have to of played in an U17 specifically for it to apply
As in they can play in an U20 and still be eligible for the U17.
Edit: though that would make the mention of "U20" above it to be redundant. So maybe it's just confusingly/poorly worded, and it does in fact mean if you compete in U20 you cannot then compete in U17. Which does seem ridiculous. I can kind of understand not being able to compete in two of the same...but if they were to compete in 2, the first time someone competes they'd probably get minimal minutes due to being so young anyway.
