PSV Eindhoven winger Dries Mertens is on the brink of signing for Napoli.

His father has confirmed a move to Italy is close.

"He thinks he'll be in Naples by the end of next week," Herman Mertens told Niewsblad. "It's a unique opportunity for him.

"His girlfriend was hoping for a transfer to London, but then Napoli arrived. When an offer from an important club like that is made then you can't say no."
