Chelsea have reportedly made Bayern Munich star Franck Ribery their top target when the transfer window opens in January.

The capital club are free to sign any player they want during the transfer window following a ruling by the Court of Arbitration for Sport (CAS) which suspended a transfer ban imposed by FIFA pending a final review.

Fifa had ruled that Chelsea could not sign players until 2011 after being found guilty of inducing Lens player Gael Kakuta to break his contract. The Blues have consistantly denied any wrongdoing - and seem set to fight the ban all the way as CAS look to make a ruling some time next year.

Chelsea chairman Bruce Buck recently announced that the west London side were looking to make a "marquee signing" as they challenge strongly for both Premier League and Champions League glory under the guidence of new coach Carlo Ancelotti.

According to a report in The Telegraph, this big name acquisition is said to be Ribery, who is believed to be unsettled by the fact that a number of clubs are chasing his signature.

And with the Bavarian side currently mired mid-table in the Bundesliga and yet to qualify for the last sixteen of the Champions League the newspaper believes that Ribery will push for a move in the new year.

Bayern reportedly refused a £40 million offer for the player from the Blues earlier this year, whilst big-spending Manchester City and Spanish giants Barcelona and Real Madrid have also showed interest in the French international.

Ribery is currently nursing a knee injury, which has had an adverse effect on his time at the Allianz Arena, limiting him to only six appearances so far this season.
