The Federation International Football Association FIFA has placed two years transfer ban on Chelsea football.
The London side will not be able to sign players for the next two transfer windows.
We gathered the club breached rules around the transfer of minors and the world football governor body also fined the club £460,000 for the offence.
Fifa looked into over 100 cases involving players under the age of 18, an investigation into deals dating back years.
Chelsea are expected to appeal the decision, a time-consuming process which could push the process into and past the upcoming summer window.
A statement reads: “Chelsea was found to have breached art. 19 of the Regulations in the case of twenty-nine (29) minor players and to have committed several other infringements relating to registration requirements for players. The club also breached art. 18bis of the Regulations in connection with two agreements it concluded concerning minors and which allowed it to influence other clubs in transfer-related matters.
“The Disciplinary Committee sanctioned Chelsea with a ban on registering new players at both national and international level for the next two (2) complete and consecutive registration periods. This ban applies to the club as a whole – with the exception of the women’s and futsal teams – and does not prevent the release of players.
“The protection of minors is a key element in FIFA’s overall regulatory framework relating to the transfer of players and effective enforcement of these rules is paramount, as also confirmed on various occasions by the Court of Arbitration for Sport.
“The decisions issued by the Disciplinary Committee were notified today and can be contested before the FIFA Appeal Committee.
There has been an inquiry into the allegation for the past three years and one of the main contentious signings was the arrival of Bertrand Traore in 2014.
The Burkina Faso forward joined Lyon in 2017 after making 16 appearances for the club.
