Milan lost 3-1 to Chelsea, playing well in the first half but collapsing when the starters were taken off.
It was the last game in the International Champions Cup for the Rossoneri, who pitted Vincenzo Montella against Antonio Conte.
In spite of fielding arguably the less prestigious team, Milan started out strong and managed to play largely as equals to the Blues during the first half.
Bertrand Traore gave the Premier League team the lead at the 34' by tapping in a shot that Gianluigi Donnarumma could not hold, but Giacomo Bonaventura's remarkable free kick at the 38' re-established parity.
Both Coaches changed almost all of their main starters in the second half, and the Italians' thinness on the bench came back to haunt them.
Chelsea took hold of the game and scored with Oscar's penalty at the 70' and his angled shot at the 87', whilst the Diavolo could not break an excellent Thibaut Courtois between the posts.
