The striker scored the only goal of the game Sunday and is hoping the result can kick start a strong finish to the season under Milan's new coach.
Milan was made to work hard to overcome the newly promoted side, with the Italy international's late penalty settling a tense affair.
The forward is delighted with the result and is hoping it can kick start a strong run in the second half of the season.
"My thumbs up towards the coach? Yes, it is a victory that we dedicate to him," he told Sky after the match. "It was the first game, obviously it was a difficult situation. We were very well organized and played very well.
"Hopefully [it can be a turning point]. Starting well is half of the battle."
AC Milan's next Serie A game is a home clash with Udinese on January 22.
