The Partenopei qualified for the tournament via the play-offs, crushing Nice 4-0 on aggregate, and have won their last 10 competitive matches.
They also started their European group stage in Ukraine last year, beating Dynamo Kiev 2-1 with a Milik brace.
The Poland international leads the way again, resting Mertens from the trident with Insigne and Jose Callejon.
