Milan are having their best start to a season in the three points for a win era, sweeping Fiorentina aside 2-0 despite Bartlomiej Dragowski’s penalty save.
The Rossoneri consolidated their lead at the top of the Serie A table with yet another victory at San Siro.
Alessio Romagnoli was allowed a free header at the back post to open the scoring on a corner.
Dusan Vlahovic’s strike was fingertipped onto the upright by Gianluigi Donnarumma and Franck Kessie converted a penalty for a foul on Alexis Saelemaekers.
Theo Hernandez went down under the Martin Caceres challenge for another spot-kick, but this time Dragowski parried from Kessie.
Hakan Calhanoglu also hit the woodwork and Donnarumma was again decisive on Franck Ribery.
