Real Madrid Director General Jose Angel Sanchez has branded the ban on registering new signings handed down by FIFA as "absolutely unjustified" and is confident the club will win an appeal.

Real and Atletico Madrid were found to have breached rules on the international transfer and registration of players aged under 18, with the sanction imposed for the next two transfer windows.

The ban does not affect the current registration period and does not prevent players leaving either club but means that, after this month's transfer window closes, neither real nor atletico will be able to register any new players until the summer of 2017.

Atletico have also been hit with a 900,000 Swiss Francs fine (£620,000) while Real have been fined 360,000 swiss francs (£250,000).
