Napoli have sacked manager Carlo Ancelotti less than three hours after he guided them into the Champions League knockout stages.
The Serie A club had not won in nine games in all competitions until Tuesday's 4-0 success at home to Genk.
Ancelotti was in his second season in charge of Napoli but they sit seventh in the league after that poor run.
They are the only team to beat Liverpool in 90 minutes this season, defeating the Reds 2-0 in September.
Last month the manager and Napoli players were in a high-profile dispute with president Aurelio de Laurentiis.
