Chelsea are following developments at Manchester City with interest after the Premier League champions avoided a transfer ban for breaching rules on under-18 signings, according to Sky Sports.
City were fined £315,000 on Tuesday, but were not given a transfer ban after FIFA revealed their admission of responsibility was a factor in determining their punishment.
Chelsea meanwhile were handed a one-year transfer ban and fined more than £460,000 in February, and are currently in the process of challenging their sanction to the Court of Arbitration for Sport.
The club have declined to comment, but it is understood they are monitoring City's situation closely as their appeal against signing new players continues.
FIFA officials clarified to Sky Sports News why City were fined less and avoided a ban for breaching the same article as Chelsea, stating the circumstances were different.
"In its decision on Manchester City, FIFA's Disciplinary Committee took into consideration all specific circumstances of the case as well as the club's cooperation in clarifying the relevant facts," a FIFA spokesperson told Sky Sports News.
"It is important to stress that the specific circumstances of this case differ from previous cases involving breaches relating to the international transfer and registration of players under the age of 18."
City said the breaches arose after a "misinterpretation of the regulations in question", adding in a statement that they have been fully compliant since December 2016.
City, who are still currently under investigations from FIFA and UEFA with regards to financial fair play, were found to have breached article 19 of the FIFA Regulations on the Status and Transfer of Players.
FIFA's statement added: "The protection of minors is a key element in FIFA's overall regulatory framework relating to the transfer of players, and the effective enforcement of these rules is paramount, as has also been confirmed on various occasions by the Court of Arbitration for Sport."
