Ismael Bennacer made San Siro erupt not long before the break as he scored his first ever Champions League goal to break the deadlock against Napoli.
Against the run of play, it was Milan who took the lead five minutes before the break. Brahim Diaz did superbly to squeeze between two markers and bear down on goal, and though his pass to the right was behind Leao he fired it back across the box to Bennacer, who finished in off the boot of Meret.
