Inter Milan defeated Napoli 1-0 thanks to Lautaro Martínez's late victor.
"You're one of the most handsome people I know, please never change".
"In Italy there are some problems in football, especially for Naples I think", Sarri said in a news conference on Friday ahead of Chelsea's clash with Crystal Palace.
As a result of the chants, Inter have been punished with a two-match stadium closure, and boss Luciano Spalletti has condemned his side's fans' actions.
Inter won courtesy of a stoppage-time victor from Lautaro Martinez - 10 minutes after Koulibaly had been dismissed - and Spalletti is disappointed that the abusers may believe they have influenced the outcome of the match. They'll probably make us lose the game if we walk off, but we're prepared to do it.
"Certainly we're not the only nation where these things happen".
Four Napoli fans were hurt and one of them was stabbed, police said.

Inter fans allegedly made animal noises and racist chants at Napoli's Senegalese defender Kalidou Koulibaly during the match, while one fan was killed when he was hit by a vehicle during a violent clash near the stadium before kick-off.
President of the Italian Football Federation Gabriele Gravina has considered suspending the Serie A, Italy's most important football league.
Koulibaly's compatriot and Senegal teammate Sadio Mane has now sent a message to the centre-back.
Also, Koulibaly was suspended for two matches - one for the red card and one for applauding the referee.
Cardona said he will request that Inter fans be banned from traveling to away games for the rest of the season and that the northern end of the San Siro, where Inter's "ultra" fans are based, be closed until March 31.
The combative, heavily-tattooed Belgian, who according to Italian media arrived late for training several times in the previous weeks, has not made the expected impact since his move from Roma in the summer, partly due to injury.
The football world has been united in its condemnation of monkey chants from Inter Milan fans towards Napoli defender Kalidou Koulibaly, with prominent figures including Mo Salah insisting racism has "no place" in the game.
