The agent of Borussia Dortmund defender Neven Subotic has confirmed the interest of Serie A clubs in the Serbia hopeful.

"I repeat: Napoli, Juventus and Fiorentina have shown strong interest, but Neven has signed a contract only six months ago and has no intention to leave Borussia now," said Steve Kelly.

"However, the doors remain open."

Kelly also told calciomercato.com: "He is now worth £3 million, but in June that will surely increase."
