Antonio Cassano's agent says there is "no possibility" of the AC Milan striker joining Napoli in an exchange deal for Marek Hamsik.

The Italy international joined the Serie A champions in January from Sampdoria and is under contract until June 2014.

Despite his promising performances for Milan, reports have linked Cassano to a possible swap which would see Slovakia midfielder Hamsik join the San Siro outfit this summer.

However, Cassano's agent Giuseppe Bozzo said to Gazzetta dello Sport: "Cassano will remain at Milan as long as he is useful to the Rossoneri club.

"Napoli? I would say those are just media inventions.

"There is no possibility that there can be an exchange between (Napoli's Marek) Hamsik and Cassano."

The 28-year-old scored four goals and provided seven assists in 17 Serie A appearances for Milan.
