Groningen striker Tim Matavz is on his way to Genoa in the summer.
Genoa had hoped to conclude a deal for the 22-year-old Slovenian in January, but a deal failed to be done in time.
Now Napoli have moved to secure a deal for him ready for the end of the season, worth around 7million.
Matavz's agent Nusret Jashari told the Gazzetta dello Sport: "The deal was protracted and it was difficult bureaucratically to define a loan [in January]. But Tim will arrive in June. There is an agreement between the two parties.
"Obviously he is happy. He wanted Napoli. He likes the stadium, the fans and the passion. When it's possible, he'll go and see a game."
