The agent of Siena fullback Juan Camilo Zuniga has confirmed big club interest.

"It's true that Juventus follows him, but especially he's liked in Spain. Also there's Fiorentina," said Riccardo Calleri. "The Viola club has always been very interested in young promising players and he is certainly a player like that.

"In that sense, I can confirm that I've had some contact with (sports director) Pantaleo Corvino, but this is my job."
