The Football Association has challenged FIFA's verdict in relation to Chelsea's transfer ban and will try and get the punishment reduced further.
In February 2019, Chelsea were handed a transfer ban for two windows and fined after being found guilty of breaching rules relating to the international transfer and registration of under-18 players.
The FA were also fined 510,000 Swiss francs (£391,000 at the time) as part of the ruling.
Chelsea appealed the verdict and their punishment was later halved to just one transfer window, meaning they couldn't sign anyone last summer but could in January.
