Balotelli's penalty gaffe helped Genoa earn a point from the San Siro.
Allegri said: "The team did everything it had to in order to win, creating chance upon chance and allowing Genoa just one shot on target throughout the 90 minutes - and that was a penalty.
"Of course Balotelli was demoralised by the penalty miss, but he did good things and is an important player for us. After the spot-kick, Genoa put 10 men behind the ball and there wasn't much space."
