Siena sporting director Stefano Antonelli has claimed that centre-back Neto is one of the best in the League.
The Portuguese defender has been linked with a January move to Juventus and Napoli, but the Robur man has admitted that they will sell for the right price.
“I believe that Neto is one of the best centre-backs in Serie A,” he told Sky Sport Italia.
“Neto and Ogbonna, considering their age, are the best. Before we sell him, we have to think hard because he has great qualities.
“But we will only sell if the right price is being offered.”
