Arkadiusz Milik scored a crucial away goal and RB Salzburg pounced on an Allan error, so it’s 1-1 on the night, Napoli 4-1 up on aggregate.
The Partenopei won the first leg 3-0, but had to thank Alex Meret for some crucial late saves in keeping the clean sheet. Kalidou Koulibaly and Nikola Maksimovic sat out bans, with Raul Albiol injured, so Vlad Chiriches and Sebastiano Luperto were the only centre-back options. Lorenzo Insigne pulled out in the warm-up, making way for Dries Mertens. Salzburg had Xaver Schlager suspended and Zlatko Junuzovic injured, but brought in Dominik Szoboszlai, Enock Mwepu and had Takumi Minamino fit again.
Arek Milik only grazed his diving header to a Fabian Ruiz cross, but it was the Poland international who got the all-important away goal.
Mario Rui caught Mwepu in possession and rolled across from the left, so Alexander Walke did all he could to prevent an Andreas Ulmer own goal, but Milik scored from the rebound with an acrobatic finish at the back post.
Allan was at fault for the equaliser, passing it straight to Szoboszlai, who threaded through for Munas Dabbur. The striker sold Chiriches with a dummy and beat Meret from close range.
Milik only scuffed the finish after Mertens surged forward and threaded his pass through the eye of a needle, then moments later Fabian Ruiz cracked one against the upright from distance.
Jerome Onguene nodded wide from a corner and Minamoto fired off target.
