Chelsea have had their transfer ban lifted by the Court of Arbitration for Sport after reaching an agreement with Lens over the signing of Gael Kakuta.
A statement on the Cas website said that the two clubs and the player had accepted the player’s contract with the French side was not valid.
Thus Kakuta could not have terminated it prematurely, so Chelsea could not be liable for inducing it to be breached.
The Cas said all parties agreed the proceedings would remain confidential.
In September 2009, Fifa’s Dispute Resolution Chamber imposed a four-month ban on the player and banned Chelsea from registering any new players in the next two transfer windows over the case.
