Napoli and Milan are discussing the possibility of swapping Paolo Cannavaro and Cristian Zaccardo.
Cannavaro’s future at the Stadio San Paolo is in doubt as the captain, 32, has lost his place in the starting XI with new boss Rafael Benitez.
His agent last week dismissed associations with the Diavolo, but the two clubs are in deadline day talks about a possible deal for the defenders before the window closes.
The San Siro giants are ready to include Zaccardo in a move seeing that he has barely featured since arriving from Parma in January.
The 2006 World Cup winner, 31, has appeared in just one League game for the San Siro giants.
Milan could also make a late bid for Cagliari centre-back Davide Astori.
