FIFA has rejected a request from Chelsea to suspend their one-year transfer ban while they challenge the sanction.
Chelsea were banned from signing players for the next two transfer windows after being found guilty of breaching rules regarding the registration of minors.
Thomas Bodstrom, the world football governing body’s appeal panel chairman, said the body will not allow the club to do business in the transfer windows while they appeal the ban.
The decision mean that the English club could challenge the decision at the Court of Arbitration for Sport (CAS), in order to get an interim ruling.
FIFA said it found Chelsea guilty of breaching article 19 of the regulations in the case of 29 minor players, as well as a number of other infringements relating to requirements for registering players
The club was also fined £460,000 and given three months to rectify the irregularities surrounding the minors involved.
Reports say Chelsea believe they have grounds for appeal. But after a full audit of over 100 transfers, the 2019 Carabao Cup finalists found a few breaches that they feel do not constitute serious offences.
In response, Chelsea said they were “astonished” by the decision not to suspend the sanction.
In a statement, the club said: “The club acted in accordance with the relevant regulations and has already notified Fifa of its intention to appeal against the disciplinary committee’s decision and sanction. As a matter of procedural fairness and equality of treatment, and Swiss law, the club’s right to an appeal process must be afforded, before any irremediable sanction takes effect.
“So far as the club is aware, in all previous cases where a registration ban has been imposed by Fifa, a decision has also been made to suspend the sanction until the appeal process has been completed. In this case, Chelsea considers that it is being treated inconsistently in comparison with other European clubs.
“We will consider our next steps once we have received the written reasons for this decision from Fifa. The club notes the appeal committee’s statement that it has the right to appeal to Cas. In the meantime the club will continue to fully cooperate with the proceedings.”
