Stefano Pioli's team suffered their first loss of the season last time out but produced a response worthy of champions, turning in an accomplished display on Saturday.
With Zlatan Ibrahimovic making a return off the bench following his recovery from injury, Rafael Leao opened the scoring before Franck Kessie's penalty made it 2-0.
Torino had a penalty of their own overturned in the second half but Andrea Belotti's poor header to end a rare attack summed up a disappointing performance, meaning their long wait for a league win at Milan goes on.
16 - #ACMilan have scored 2+ goals in 16 league matches so far: no side have managed a better such tally in the #SerieA history during the first half of the season (also Internazionale did so in 16 games in 1949-50 and in 1950-51).
