Arsenal boss Arsene Wenger cannot believe he faces losing Ryo Miyaichi to an unusual U22 call-up by Japan.
Wenger was asked about the situation after their draw with New York Red Bulls.
He told arsenal.com: "We have now in football the Under-16, Under-17, Under-18, Under-19, Under-20, Under-21, Under-22 soon we will create the Under-60 and we'll have to let the players go.
"I think at some stage the clubs should be within in their rights to use their players because these competitions are organised when the season is already started. I think we have to become serious. Players under 20? You take our midfield from yesterday. Frimpong is 19, Ramsey is 20, and Wilshere is 19.
"They can now play in the World Cup Under-20, so we could be in a situation where we could lose our players and cannot even field our midfield. That's where people inside the clubs raise questions about how we can continue to give a chance to young players if during the season they go away with the national teams."
