Napoli’s hopes of being crowned Serie A champions on Sunday were delayed, after being held to a 1-1 draw by Salernitana at home.
Nigerian striker Victor Osimhen was in action as Napoli looked set to clinch its first league title since 1990.
Luciano Spalletti’s side needed to win after Inter Milan came from a goal down to beat Lazio 3-1.
But Senegalese forward Boulaye Dia scored in the 84th minute to cancel Mathias Olivera‘s 62nd-minute opener.
The draw against Salernitana means Napoli are now 18 points ahead of second-placed Lazio on the log.
