FC Sion have opened negotiations to sign Liverpool striker Mario Balotelli, the Swiss club's president Christian Constantin has claimed.

Balotelli, 26, is free to leave Anfield this summer, having been frozen out by manager Jurgen Klopp, who said in July that the Italian was not in his plans.

Besiktas, Sassuolo, Bologna and Nantes have all been touted as possible destinations for Balotelli, and Constantin has now claimed Sion are negotiating with the Liverpool striker's entourage.

"I can confirm that we are talking and negotiations are underway" he told ticinonews.ch. "Obviously I cannot know whether it will have a positive conclusion or not."
