Napoli have completed the signing of Arkadiusz Milik from Ajax for an initial €32 million.

Aurelio De Laurentiis has confirmed Napoli have signed striker Milik, as the Poland international joined the Italian team for a pre-season friendly.

The 22-year-old attended Napoli's game against Nice at Stadio San Paolo on Monday and an official announcement confirming the signing of a reported five-year contract is believed to be imminent.

Milik, whose reported transfer fee is around €34 million, will face a tough task to replace Gonzalo Higuain at Napoli after the Argentine left to join Serie A champions Juventus in a deal worth €90m.

Napoli have made two major signings since the end of last season, bringing in defender Lorenzo Tonelli from Empoli and signing Italy international Emanuele Giaccherini from Sunderland.
