Luis Muriel netted a last-minute winner for Atalanta in style as his back heel broke Milan hearts following a tense clash.
La Dea took a 1-0 lead after 38 minutes but Olivier Giroud’s equaliser just before the break kept things level heading into the second half. Ademola Lookman found his brace just before the hour mark and it took 25 minutes for Milan to respond through Luka Jovic.
Tensions continued to climb as the match started to draw to a close, with Davide Calabria seeing a second yellow card, and Muriel ended things in sensational style with his last-minute winner.
