At the final whistle, the Stadio Artemio Franchi jeered them off the field and called for Mihajlovic to be sacked.
"We are going through a complicated moment, but played a great game today," assured Jovetic after his brace.
"It was a shame to concede two goals in that fashion. I'm sorry about the jeering, as neither Mihajlovic nor the team deserve this reaction.
"We gave our all this evening. I am glad I renewed my contract, but there is only one leader at Fiorentina and that's the Coach."
