Kalidou Koulibaly was shown a straight red card as Napoli extended their unbeaten Serie A run to 11 games this season with a 1-0 victory over Salernitana on Sunday.
The Senegal international was sent off for his reckless tackle that stopped Nigeria striker Simy Nwankwo from converting a goal-scoring opportunity in the 76th minute.
It was the first time in two years that Kouibaly was shown a straight red card in the Italian top-flight, since his sending off against Cagliari in September 2019.
Prior to his expulsion, Napoli had secured maximum points at the Stadio Arechi after Piotr Zielinski separated both teams with his only goal in the 61st minute.
