"Today we are very happy, as this was a great performance despite missing important players," the Milan boss told Sky Sport Italia.
"It was a great victory, we should enjoy it, but I am already looking forward to Fiorentina. I can say two consecutive wins represent a fine boost for this team.
"The players make me proud to train them. When I see them working, I am relaxed and know they are doing everything right. Of course on the field things can take a different turn and I didn't expect to be 3-0 up in a tough arena like this."
The result saw Milan climb to fourth by stretching their unbeaten run to four games.
