While Henrique is on his way, Napoli are also close to signing Faouzi Ghoulam from Saint-Etienne for €3.5m.
The Partenopei have been very active during the January transfer window, already bringing in midfielder Jorginho from Hellas Verona and defender Henrique from Palmeiras.
Now Sky Sport Italia claim they are very close to their next target, left-back Ghoulam of Saint-Etienne.
The Algeria international can also play centre-back and on the left wing, making 19 appearances for the club in all competition this season.
Ghoulam turns 23 on Saturday and has a contract until June 2016, but it’s reported Napoli have agreed a €3.5m transfer fee.
