Corini's second spell in charge of the club came to an end after Chievo lost five of their first seven matches of the 2014-15 Serie A campaign.
He became the first coach to lose his job in the Italian top flight this season, and Chievo have acted swiftly in finding a replacement.
Maran spent nine years at the club ias a player n the 1980s and 90s, making 330 appearances, and the 51-year-old is tasked with steering the team away from the relegation zone.

"For me it is a great thrill," he said. "It is a double joy because I lived almost my entire career at Chievo as a player.
"Now I return as coach, I hope to relive the emotions experienced during those years.
