Atletico Madrid unable to sign players until 2018 after losing transfer ban appeal

- Atletico Madrid's transfer ban till January 2018 has been upheld by FIFA despite an appeal - Diego Simeone's side submitted a final appeal to have the ban overturned but it was rejected - The move will force Atletico Madrid to reject transfer bids from other clubs for their players - The ban will force Antoine Griezmann's move to Manchester United to be called off Antoine Griezmann's move to Manchester United has been called off after Atletico Madrid saw their FIFA-imposed transfer ban upheld after submitting a final appeal to the Court of Arbitration for Sport (CAS).
The Spanish club will not be able to register any new players until January 2018 which could affect their summer transfer business.

Atletico were given a two-transfer window ban and the club were hoping that a successful appeal would see the ban reduced to just one, which had already been served in January 2017. 
City rivals Real Madrid were issued with a similar ban at the same time but have already seen theirs reduced. Diego Simeone's side will be able to sign new players, but they will not be able to officially register them for competition until next year similar to what Barcelona did when they signed Aleix Vidal and Arda Turan in 2015 while serving a ban.

Atletico have agreed a move for Lyon's Alexandre Lacazette last month but that move is doomed to fail while any chance of Diego Costa returning from Chelsea is likely dead.
