As punishment for a reported attempt to haveGaël Kakuta abandonLens' youth team,Chelsea were originally banned byFIFA from signing new players during the winter period; however, theCourt of Arbitration for Sport suspended the transfer ban, which will allowChelsea to sign new players.[1]Portsmouth had a transfer embargo placed on them but it was removed, which allowedPortsmouth to only sign players for Free or on Loan.[2]The wintertransfer window opened on 1 January 2010, although a few transfers took place prior to that date. The window closed at 17:00 on 1 February. Players without a club may join at any time. Clubs below Premiership level may also sign players on loan at any time. Clubs may also sign a goalkeeper on an emergency loan, if all others are unavailable.
