Napoli continued their red-hot start to the 2017/18 season with a convincing 3-1 win over Feyenoord in the Champions League on Tuesday night.
Lorenzo Insigne broke the deadlock in the seventh minute before Dries Mertens opened his account in Europe just after half-time.
Jose Callejon then made it 3-0 with 20 minutes remaining to put the game to bed, though Feyenoord did score a stoppage-time consolation through Nordin Amrabat.
Victory at the Stadio San Paulo meant Napoli made up for their 2-1 defeat at Shakhtar Donetsk two weeks ago, but they remain third in Group F.
Next up is group-leaders Manchester City, who they face at the Etihad Stadium on October 17.
Napoli have been sensational so far this season, winning each of their opening six Serie A games to lead the away in the table above reigning champions Juventus.
Twenty-two goals scored and just five conceded tells you all you need to know about how good Maurizio Sarri's side have been thus far.
Saturday's narrow 3-2 win away to SPAL was yet another statement of intent from Napoli - but it came at a price.
Having only recently recovered from ligament damage to his left knee that kept him out for most of last season, striker Arkadiusz Milik suffered heartbreak once again by injuring his right knee.
Team doctor Alfonso De Nicola explained on Tuesday afternoon that the injury wasn't a result of Milik being rushed back too soon, saying: "There was damage to the right knee.
"It must be said that people who conflate the two things are ignorant and don't understand the essence of these things.
"You can't link these two injuries. Unfortunately these things happen in football. After a knee injury, some injuries can occur. The previous rehabilitation was done correctly."
Milik is expected to be out for a very long time - he won't be able to exercise his knee until December - which has upset his Napoli teammates.
As a way of showing strength and support, Insigne decided to dedicate his goal against Feyenoord to Milik by holding up his shirt to the home fans.
Except it went horribly wrong. In the video below, Insigne is thrown a Napoli shirt but when he holds it open, it has the wrong name on it.
Quite hilariously, it read 'Zielinski', as opposed to 'Milik'. Check it out.
INSIGNE'S TRIBUTE BLUNDER
Luckily for Piotr Zielinski, Insigne saw the funny side of his error and simply swapped the shirts over to hold 'Milik 99' instead. Class.
