Livorno President Aldo Spinelli claimed “nothing has changed since Calciopoli” after his team was relegated.
The Amaranto went down after a 1-0 home defeat to Fiorentina, while Sassuolo survived by beating Genoa 4-2.
“I am selling the club, I can’t take it anymore,” Spinelli told the Corriere dello Sport-Stadio.
“I’m so tired of this world and want to just enjoy my weekends from now on, so no more football.
“Certain things make me nauseous and I can say that in the light of what happened in recent games. Some results, some games...
“People said that after Luciano Moggi and Calciopoli football had been cleaned up, but nothing has changed!
“Did you see Sassuolo-Genoa? There are four Genoa-owned players at Sassuolo and they’d have been forced to go back if the Neroverdi dropped out of Serie A. These things hurt.
“Livorno were damaged too, as the only real game last Sunday was Bologna-Catania.”
Livorno are bottom of the Serie A table with just six wins all season, seven draws and 24 defeats.
The Amaranto also have the worst defensive record in the top flight, conceding 75 goals.
