The agent has suggested that the striker could leave the Stadio San Paolo at the end of the season to join one of five clubs, including Barcelona, Real Madrid and Manchester City
The Uruguayan’s future has been subject of speculation for some time, with interest from teams such as Chelsea and Manchester City being reported ahead of the January transfer window.
The agent, however, has said that he fully expects Cavani to move from Naples at the end of the season, but claimed that only one of five teams have the funds to afford the striker.
"For now Cavani will stay, but I wouldn’t be so sure about that once June arrives," Raiola told Il Mattino.
"I’m sure there are clubs ready to pay that [€63 million buy-out clause] in the summer, but only five clubs in the world can afford to do that - Barcelona, Real Madrid, Manchester City, Chelsea and Paris Saint Germain.
"You are intelligent enough on your own to understand where Cavani will play his football next season."
The Serie A side revealed after Christmas that they had rejected a bid of €55m for the Uruguay international.
