Former Inter Milan coach Gigi Simoni has questioned the timing of Walter Mazzarri's dismissal.
Roberto Mancini's first game in charge will be the derby against AC Milan.
"I think that Mazzarri is a good Coach," Simoni, who coached Inter in 1997-98, told ilveroMilanista.it.
"I would not have sacked him before the derby, because in the event of a positive match for the Nerazzurri, I think that it could have completely changed his position and the start to the season.
"I do not know why come out of bringing in Roberto Mancini a few days before this important game."
