Uefa, the governing body of European football, states that the ruling only affects the transfer of players no longer under contract. It is therefore still possible to obtain a transfer fee for a player under contract, irrespective of where the player is transferred to.
If a player is no longer under contract and is transferred from a club in one member state of the European Union to a club in another member state, then it is no longer possible to obtain a transfer fee. But this only applies if the player is also a national of one of the EU member states.
If a player is transferred from one English club to another then it is possible to obtain a transfer fee. The same applies if a player moves from an English club to a Scottish club as the transfer takes place within a single EU member state. The changes apply from 15 December.
Restrictions on the number of EU nationals who may play in teams in domestic competitions are illegal. Restrictions on non-EU nationals who can play in European club competitions remain in place, as teams are said to be "representing their countries".
