Domenico Di Carlo has become the third coaching appointment of the day after Chievo confirmed his arrival.
Sampdoria and Catania had already announced Gianluca Atzori and Vincenzo Montella respectively, before Chievo completed the hat-trick.
Di Carlo, sacked by Sampdoria this season, has signed a one-year contract with the club which he has already bossed in the past.
The former Vicenza midfielder joined Chievo in the autumn of 2008 and kept them in the top-flight for two seasons before moving to Marassi.
Di Carlo will be presented to the media on Friday at a hotel in Verona.
