The decorated coach is said to be at odds with the club's president at a time when positive results have been at a premium
Lorenzo Insigne mounted a strong defence of Napoli head coach Carlo Ancelotti following the frustrating 1-1 Champions League draw against Salzburg.
Hirving Lozano cancelled out Erling Haaland's early opener at Stadio San Paolo but the Serie A side failed to find the winner that would have confirmed their place in the knockout rounds.
Tuesday's draw extended Napoli's winless run to four games in all competitions and Ancelotti's failure to appear for the customary post-match news conference did nothing to dispel rumours of division at the club.
