Mexico international Hirving Lozano arrived in Italy on Tuesday ahead of his expected move to Napoli from PSV.
Lozano is expected to join the Partenopei in a transfer worth a reported €42 million (£38.5m/$47m).
The 24-year-old winger has been linked with the Naples club for much of the transfer window and completion of the deal appears close.
Lozano was mobbed by a group of Napoli supporters shortly after arriving at an airport in Rome, posing for photographs with fans displaying club merchandise.
A direct, goalscoring winger, Lozano has enjoyed two excellent seasons with PSV in the Eredivisie.
Having joined from Pachuca in 2017 after building a fine reputation for himself at home in Mexico, Lozano seamlessly settled into Dutch football.
He scored 17 league goals and added eight assists in his first campaign, resulting in speculation linking him with more illustrious European clubs, such as Manchester United.
Although Lozano was not able to inspire PSV to the title again last term, he proved his debut season was no fluke by accumulating the same number of goals and assists.
Lozano has already played one match with PSV this season, though he picked up a knock against ADO Den Haag on August 11 that ruled him out for this weekend's game against Heracles.
The injury may yet rule Lozano out for Napoli's Serie A opener against Fiorentina on Saturday, as the Partenopei look to go one better this season following back-to-back second place finishes behind Juventus in the Italian top flight.
Also known for his blistering pace, Lozano has been capped 35 times by Mexico and is generally regarded as one of the country's most talented exports since Real Madrid icon Hugo Sanchez.
Lozano will reportedly undergo a medical on Wednesday.
The Mexico star's arrival may also shut the door on a possible move for James Rodriguez, who has been linked with a switch from Real Madrid all summer.
The Colombia international has returned to Madrid after spending two seasons on loan with Bayern Munich, but his path to playing time at the Bernabeu is unclear.
Rodriguez was an unused substitute in Madrid's 3-1 win over Celta Vigo at the weekend in their La Liga opener.
