Man Utd's Alejandro Garnacho among breakout stars missing from U20 World Cup

Some of the world's best young footballers won't be playing in the Under-20s World Cup in Argentina this month with clubs reluctant to release them before the end of the season. FIFA took the decision to stage the tournament outside the international window and before most European domestic seasons have been completed. I've spoken to FIFA about it this morning and they've told me that this tournament is normally staged early outside of the international window so this isn't setting a precedent or anything like that and they said they had little choice here despite pressure from a number of FAs to try and shift it later because there are so many other big summer tournaments happening. You've got the Women's World Cup, you've got the Men's Under-21s Euros, you've got the Men's and Women's Under-17s Euros and those are all scheduled between May and July but what I understand the FA contacted FIFA about was to say look you allow us to change squads up until the first game until match day minus one the day before the first game we're allowed to change our squads if players get injured well because of this availability problem can you let us change our squads depending on who's available and FIFA came back and said no and FIFA have explained that to me today they say look fairness to all countries is key here it's a standard rule they have throughout all of their tournaments that you can only change players that you've named in a squad if one of those players gets injured and you withdraw them from the squad so they didn't want to make an exception here and I understand that England's Under-20s manager Ian Foster has had a real problem here he announced his squad earlier today but it was supposed to be announced more than 24 hours ago he's been constantly on the phone to clubs in England and in Europe to try and get the players released that he wants to be in his squad in terms of who's out Rico Lewis Manchester City's player has been so impressive this season he's not in although we should say as a little footnote that I mentioned the Under-21s Euros he may well be in that squad for England's Under-21s Euros stepping up a level so don't read too much into that but Lewis Hall at Chelsea Jamie Baino-Gittins at Borussia Dortmund Samuel Ilung Jr at Juventus are not going to be in this England squad
