Catania have sacked Rolando Maran following last night's 2-1 defeat at Cagliari.
The 50-year-old, who was named as Vincenzo Montella's successor last June, last leaves the Elefantini just above the relegation zone in Serie A with one win from their opening eight games.
Former Genoa manager Luigi De Canio has been installed as his replacement.
"Calcio Catania announce they have removed Rolando Maran from his position," read a statement on the club's official website.
"We give him our most heartfelt thanks for the work done and wish him the best for his on-going career. The first team has been handed to Luigi De Canio."
De Canio has been without a club since being fired by the Grifone in October last year.
