FIFA have upheld the transfer bans against Real Madrid and Atletico Madrid.

Neither club can register players during the next two transfer windows and will have to wait until January 2018 to make any new signings.

Fifa said that its rules, which ban international transfers of under-18 players except in certain circumstances, existed to “protect minors who move to other countries and prevent soccer clubs from exploiting them.”

Real Madrid and Atleti have met in two of the past three Champions League Finals.
