Barcelona registered a hard-fought draw following a 1-1 scoreline with hosts Napoli in the first leg of Champions League last 16 tie.
Dries Mertens opened the scoring for Napoli in the first half before Antoine Griezmann grabbed the leveler in the second half. This was Griezmann's first away Champions League goal since February 2017 while Mertens strike saw him equal Hamsik’s record as the club’s all-time leading goalscorer.
Napoli took the lead in the 30th minute and it was Dries Mertens with a brilliant strike that saw him equal Hamsik’s record as the club’s all-time leading goalscorer. Gattuso's game plan appeared to be working a treat as the home side broke at pace down the right with Piotr Zielinski and the low cross was collected by Mertens, who cut inside onto his right foot and unleashed an unerring strike into the top left corner beyond Marc-Andre ter Stegen for his 121st Napoli goal.
Dries Mertens' opener against Barcelona was his 121st goal for Napoli in all competitions, moving him to level with Marek Hamsik as the joint-top scorer in the club's history.
In the second half, Barcelona finally got the equalizer. Mario Rui switched off at left-back as Busquests found the overlapping run of Nelson Semedo and the low cross was blasted first time into the top corner by Antoine Griezmann to give David Ospina no chance.
Arturo Vidal loses it and receives two yellow cards in the space of a minute. First, he is cautioned for a foul on Mario Rui, and then he collected a second booking for rubbing heads with the Napoli man, who took a booking for his role in the confrontation. Vidal had few complaints and he was getting the treatment from the Napoli fans as he left the pitch.
