Chelsea have confirmed they will take their case to the Court of Arbitration for Sport (CAS) after the club's appeal against a transfer ban was rejected by Federation Internationale de Football Association.
The club had appealed against FIFA's decision to hand them a transfer ban.
Maurizio Sarri said Chelsea have no chance of competing with Manchester City and Liverpool next season unless their two-window transfer ban is overturned.
Chelsea can now appeal to the Court of Arbitration for Sport in a bid to get the ban turned over.
Chelsea can still appeal to the Court of Arbitration for Sport and that could either lead to the Federation Internationale de Football Association decision being overturned or a stay in the execution of the ban this summer while the higher court's ruling is awaited, but as it stands the Premier League club will go into the 2019-20 campaign with what Sarri has at his disposal now plus Christian Pulisic, who was signed from Borussia Dortmund for 64 million euros in the January window.
This ban applied to the club as a whole - with the exception of the women's and futsal teams - and did not prevent the release of players.
The USMNT international's transfer was completed in the 2019 January window before he was loaned back to Borussia Dortmund for the remainder of the season.
Interestingly, FIFA opted to slam Chelsea, after carrying out a probe into their transfer deals involving under-18 foreign players. "So it's not easy, because the level of the top two is very, very high", Sarri said at a news conference Wednesday after the verdict was announced. I think we have to buy only one or two players. Though, the FA have a chance to appeal the fine, citing "concerns" with FIFA's disciplinary processes according to Sky Sport.
Chelsea had been eager to have the ban lifted, or suspended pending an appeal, so they could be in a position to sign a replacement for Belgium's Eden Hazard, who is being touted as a possible £100 million (116 million euros, $131 million) transfer target for Real Madrid.
Part of Chelsea's appeal was upheld, and the club will now be allowed to register players under the age of 16.
