In February 2019, Chelsea were banned by FIFA from signing new players for two transfer windows. The ban was handed following breach of international transfer and registration of players under the age of 18. However, the club still reserved the right to appeal to Court of Arbitration for Sport. In December 2019, the ban was reduced by CAS ahead of January transfer window. However, the club in its statement said that FIFA's conduct was “deeply unsatisfactory".“The approach taken by FIFA to this case has been deeply unsatisfactory, not least as FIFA chose to treat Chelsea entirely differently to Manchester City for reasons that make absolutely no sense to Chelsea,” a club's statement read.
