Cosmi had only been appointed on February 28, shortly after Rossi's dismissal following a 7-0 home defeat to Udinese.

A short statement from Palermo said: "Palermo announces it has dismissed Serse Cosmi as first team coach and recalled Delio Rossi as his replacement."

Cosmi lost his first two games in charge but steered the team to a 1-0 victory over Serie A leaders AC Milan before the international break.

Today's defeat in the Sicilian derby left Palermo in eighth place, seven points behind Roma, who hold the last European qualifying spot.

Palermo host Cesena next weekend.
