Visiting side Napoli have not won at the San Siro since 1986, when Diego Maradona was still a fixture at the club.
Maradona's compatriot Gonzalo Higuain took up the legend's mantle to score the team's second goal after Miguel Britos had given Rafa Benitez's side the lead, but plaudits must be given to goalkeeper Pepe Reina for keeping out Balotelli's second half penalty, before the former Manchester City man hit home a consolation late in the game.
Not content with his positive contribution, Balotelli approached match officials after the fixture to express his dissatisfaction at the referee's performance, which led to him being shown a second yellow card for dissent and sent off.
Allegri told Sky Sport Italia that he could have done without Balotelli's moment of madness after the defeat.
"When games are over it’s better to stay quiet and I am against hysteria,” Allegri shared.
“It’s best to shut up and leave rather than stay there arguing with the referee, as it’s not going to change anything. Balotelli needs to improve that."
With just one win out of four Serie A games so far, the Rossoneri find themselves in the bottom half of the table, but Allegri expects the club's fortunes to improve once his key men return from injury.
"We must try to pick up as many points as possible now. Napoli are one of the candidates for the Scudetto and we played on a par with them overall despite missing many key players," Allegri pointed out.
“I already have ideas on how to fix things, but I need some of the players to recover from injuries first."
AC Milan travel to Bologna for the teams' Serie A fixture on Wednesday.
