Struggling Serie A side Palermo are on the lookout for a new coach following the resignation of Eugenio Corini.
The 46-year-old former Chievo manager steps down after just two months and one win, one draw and five defeats from seven games.
He becomes the third man to leave the struggling club this season, following Davide Ballardini and Roberto De Zerbi out of the Stadio Renzo Barbera.
Speaking to the press outside of the club, he said: "This is a decision that I've taken with integrity and lucidness, which makes me feel great pain, but which seems the fairest and most logical option right now.
"I have said many times what I think of this club and its supporters and I repeat that this affection and respect will remain unaffected."
Palermo president Maurizio Zamparini will now seek to replace Corini, who played for Rosanero for four years, with Ballardini reportedly tipped make a return to the club for a fourth time.
Just last season he was appointed, fired and re-hired, having previously taken charge of the side from 2008 to 2009.
Palermo have won just twice this season and are currently second from bottom on the Serie A standings, with 10 points from 21 games.
