The agent of Napoli wing-back Juan Camilo Zuniga has revealed the interest of Barcelona.

Ricardo Calleri says Barca are also following Pescara youngster Juan Fernando Quintero.

"Barcelona not only continues to follow Zuniga, but also Quintero. In England and in Spain more teams are interested in Zúniga, but I think it is normal because he is an interesting player for many teams because of his versatility," said Calleri.

"He could be useful for a really big club."
