Find out what clubs must do to make an international transfer
When there is an international transfer, the buying and selling clubs have to register it on FIFA's Transfer Matching System (TMS) in order for international clearance to be generated.
The buying club have to upload all the information to the system and the foreign club have to match all the details.
Then the buying club's FA will request clearance and, as long everything matches, the foreign association will issue clearance to the FA, who then informs the club and League.
In the case of Premier League, who receives a copy because they need to ensure that players coming in have had their registration transferred to the country, or Wales in the case of Welsh clubs.
