D'Aversa was axed after headbutting Verona Thomas Henry at the end of their weekend clash.
He has now been replaced by Luca Gotti and Corvino said: "I asked Gotti to accept the challenge and he did. We have done everything possible on the market with our resources.

"There must be a culture of falls. We must get used to defeats so that we can get up again. I'm not a hypocrite, I give my best. What happened on Sunday struck me a lot. I've known D'Aversa for 25 years, he's a correct person, he's a decent person. He didn't do what he did because he was violent.
"It leaves a mark on me that, despite 66 consecutive games in Serie A in the safety zone, we must always be criticised harshly. Gotti is the best on the market and he accepted immediately."
