UEFA has said that all the countries participating in Euro 2016 have to have the same number of players, despite the current collective bargaining agreement.
The governing body said in a statement on Monday that “every member of the European Union must have the number of playing positions equal to that of their population.”
While this is technically true, UEFA is not able to control every detail of the Euro, and its members must take into account how many players are available, according to the statement.
It added that, as long as the countries involved are not competing at the same level, they have to abide by the rules of the tournament.
However, if the number is too small, UEFA has the right to limit the number.
The European Football Association has been criticized for limiting the number, with some claiming that the rules should be changed.
