Despite missing an early penalty, Napoli bounced back from its first league defeat of the season to beat 10-man Sampdoria 2-0 and extend its lead at the top of Serie A on Sunday.
In an emotional match at Stadio Luigi Ferraris, Victor Osimhen opened the scoring in the 19th minute after Matteo Politano had seen his penalty saved.
Any chance Sampdoria had of getting back into the match diminished when Tomás Rincón was sent off shortly before halftime and Napoli sealed the result with another penalty.
Napoli moved seven points clear of second-placed Juventus although defending champion AC Milan can cut the gap back to five points if it beats Roma later.
Clashes took place earlier in the day between Roma fans traveling to Milan and Napoli supporters heading to Genoa. Around 300 fans were involved, throwing flares, stones and other objects at each other, causing part of the motorway to be closed and lengthy lines to form.
There were video tributes before the match to former Sampdoria players Gianluca Vialli and Siniša Mihajlović, who both died recently.
There were also plenty of banners in the stands dedicated to them and chants throughout the match.
The Sampdoria players warmed up wearing special jerseys with Vialli’s name on as well as the number nine he wore when he played for the team. Flowers were also laid by the side of the field by members of the Sampdoria staff and the Italy players from Napoli.
Vialli, who died on Friday, helped Sampdoria to its only Serie A title and three Italian Cups as well as the European Cup final during an eight-year stint.
