Palermo's celebrations over a 1000th game in Serie A were short-lived, as Torino inflicted upon them a record fourth home loss in a row.
Palermo's 1000th Serie A match ended with a disappointing 4-1 defeat to Torino that marks their worst run of form at home in the top flight.
Roberto De Zerbi's side suffered a fourth-straight league loss at the Renzo Barbera thanks to a double from Adem Ljajic and a goal each for Marco Benassi and Daniele Baselli.
The match was played out in near total darkness after a floodlight failure just after the 85th minute, with referee Michael Fabbri opting to allow play to continue to full-time as supporters held up mobile phones to shed some faint light on proceedings.
The victory fired high-flying Torino above Napoli into fourth place, while Palermo remain in the bottom three with just one win from their first eight matches.
However, De Zerbi - who watched Ivaylo Chochev score his side's first home Serie A goal of the season after just five minutes - felt the scoreline was harsh.
"I'm disappointed, because in terms of the scoreline, it was a big defeat," he told Sky.
"We knew we were facing a very strong team who will finish not far behind the big clubs, although I think I can say that the scoreline was harsh.
"Of course you can lose, but a team that wants to avoid relegation has got to turn defeats around. Our mentality won't change, but changes will be made."
