Milan coach Massimiliano Allegri identified two key games after his side landed an 18th Serie A title following a 0-0 draw at Roma.
Allegri singled out the last derby against rivals Inter as one of the keys to final victory. Milan beat Inter 3-0 a month ago despite being without star forward Zlatan Ibrahimovic.
Inter could have gone top with victory but instead Milan opened up a five-point gap between the pair.
And the other crucial clash, according to the boss, was the very next game, a 2-1 win at Fiorentina.
“There were two important games in this period, one was the derby which stretched our lead over Inter,” said Allegri.
“But the most difficult game was in Florence. Inter had won on the Saturday night and Napoli had won in the (Sunday) afternoon so we had to win not to lose our advantage.
“The team showed desire and technique and that was very important.”
