Serie A Bosman List: Samuel, Abbiati and all the players available for free in Italy this summer

With the winter transfer window opening in less than three weeks' time, Serie A's clubs are running the risk of losing those players whose deals run out in the summer, and Walter Samuel and Christian Abbiati head the list of footballers who have the ability to sign precontract agreements with a new side without their present employers' say-so once 2013 arrives.

The Inter center back has the option of an extra year on his deal at Appiano Gentile, which would allow him to extend his current contract until the summer of 2014, but as things stand the Argentine could open talks with another club come January 1.

Meanwhile, AC Milan club captain Massimo Ambrosini could mark his 15-year anniversary with the club by waving goodbye in the New Year. He is also approaching the final six months of his deal, a similar scenario to goalkeeper Abbiati, who has largely remained as the Rossoneri's first-choice shot-stopper for the past five seasons. The two 35-year-olds have not come to any agreement over new terms with the Diavolo, and, with the club having decided in recent seasons to wait until late in the campaign to discuss new deals, there is room for the players in question to maneuver.

Elsewhere, names such as Vincenzo Iaquinta, Andrea Consigli, Fabrizio Miccoli and Rolando Bianchi stand out among those who are available on free transfers across Serie A, while Javier Zanetti's contract at Inter is also up for renewal come next June, but the chances of him appearing in another club's shirt are remote at the very least.

Champion Juventus is one of four clubs who have just two players left to negotiate with or run the risk of losing, while Chievo and Siena are the two outfits facing a busy 2013 in the transfer market, with 14 of their squad members still uncertain of their whereabouts come September 1 next year.
