Victor Osimhen missed one penalty but scored another to give Napoli a narrow win over Fiorentina in their first home match since winning the Serie A title.
Osimhen found the net with a 74th-minute penalty after Nicolas Gonzalez fouled Khvicha Kvaratskhelia in the penalty area.
Fiorentina keeper Pietro Terracciano had saved the forward’s spot-kick in the 48th minute.
Napoli won a first Scudetto in 33 years on Sunday after a draw with Udinese.
And they were given a guard of hour from the Fiorentina players ahead of kick-off at Diego Armando Maradona Stadium.
