Chelsea transfer ban is suspended :

Chelsea's transfer ban has been suspended by the Court of Arbitration for Sport (Cas) pending a final review.
Fifa had ruled the club could not sign players until 2011 after inducing Gael Kakuta to break his Lens contract.
But Chelsea appealed to Cas, which said on Friday: "Such sanctions are now stayed until a final decision."
The decision means Chelsea can sign players in January, though manager Carlo Ancelotti stated he is happy with the players currently at his disposal.
