Chelsea have hit out at FIFA for treating them "entirely differently to Manchester City" over transfer breaches after the London club had their registration ban halved by the Court of Arbitration for Sport (CAS).

The Premier League side were banned from registering new players for two successive transfer windows by FIFA in February, a punishment handed down for breaching rules related to acquiring and registering players under the age of 18.

An appeal to FIFA had been partially upheld, allowing them to sign players 16 or younger, but Friday's announcement means they will now be able to buy reinforcements for their senior team in January.

Chelsea have since taken the opportunity to lambast FIFA's treatment of them, convinced they were dealt a crueller hand than Manchester City, who avoided a transfer ban in August despite the world's governing body finding them to have breached rules on under-18 signings.
