Mihajlovic's job was hanging by a thread and today's 1-0 win over Genoa was their first in over a month, yet the crowd still chanted calling for his dismissal.
"Despite the scepticism, the lads proved they are a united and compact group," said Mihajlovic.
"We're taking it one game at a time now, but deserve to have two or three extra points in the table. We dominated today against a Genoa side in good shape and should've gone 2-0 up with Alessandro Gamberini.
"It's a shame about the jeers and my players were sad at the final whistle, because obviously they were upset at being insulted after a victory. Of course the fans have the right to do what they want.
"I believe the supporters have a problem specifically with me, so let them aim their insults at me and focus on supporting the team. This isn't helping anyone."
