Enzo Maresca failed to mention his former paymasters as he shared his first message following his acrimonious exit from Chelsea on New Year's Day.
The Italian, 45, left the club following an explosive row with the west London club's owners, with a power struggle at the heart of his departure.
Chelsea later briefed that a number of episodes left them unimpressed and questioned Maresca's professionalism in a public slinging match.
And Maresca failed to mention his superiors as he posted a heartfelt message to his former plans and fans on Tuesday.
'“LEAVE THIS WORLD A LITTLE BETTER THAN YOU FOUND IT”,' his Instagram post started.
