Parma have just sacked Fabio Liverani and replaced him with D'Aversa.
"We're a little behind in the table right now, but there's time to make up for that," said Inzaghi.
“The performance against Fiorentina wasn't as attractive as we'd like, but it was a show of great character and concentration. It was not an easy game to win.
“Tomorrow will be very difficult, as Parma changed coach, bringing back Roberto D'Aversa, who will already know what needs to be done. I feel bad for Fabio Liverani, as he is a friend and a good coach, so I'm sure he'll be back soon.
“This is an important week with the derby coming up, but we must try to focus on one game at a time. Parma are your classic banana skin of a fixture, we don't want to slip up. They have excellent players and we need to be ready."
