"We are working on Savio of Brescia, and we are well advanced," confirmed Nani to Mediaset.
Savio's agent Patrick Bastianelli expects the deal to West Ham to go through soon.
"The player is very close to West Ham," he admitted to the Italian press over the weekend.
"Savio will go away soon, and the boy is happy to find Zola, a great coach and with him he will only embrace an important technical programme from which he will only grow and improve.
"West Ham have accelerated the negotiations."
