Chelsea have been banned from signing players in the next two transfer windows following a FIFA investigation.
It found them guilty of breaching the rules regarding their transfer dealings involving foreign players under the age of 18, with it coming at the end of a lengthy investigation into how they have registered players over the last few years into their academy.
It is a huge blow ahead of next season, with Chelsea currently locked in a battle to get back into the Champions League with Manchester United and Arsenal.
An official FIFA statement read: “The FIFA Disciplinary Committee has sanctioned the English club Chelsea FC and The Football Association for breaches relating to the international transfer and registration of players under the age of 18.
“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.
“Additionally, the club was fined CHF 600,000 and given a period of 90 days to regularise the situation of the minor players concerned.
“The Football Association was also found to have breached the rules in connection with minors. It was fined CHF 510,000 and given a period of six months to address the situation concerning the international transfer and first registration of minors in football.”
