AC Milan still have to fight hard in snatching that final Europa League spot for next season as they picked up a disappointing defeat over Atalanta.
Playing away from home didn't stop Milan from putting on an aggressive display since kick off, but the Rossoneri can't maintain their early pressure.
Atalanta starting to get a foot hold on that weekend tie as they pushed forward from their wide players.
After a goalless first 45 minutes, things finally opened up in the second half as Milan took their chance by getting the opener through an own goal from Gianpaolo Bellini on 51 minutes.
Rossoneri started to dominate things after taking that lead, but a defensive error allowed Atalanta a way back as they earned a spot kick which was perfectly executed by German Denis on 68 minutes.
Both teams had chances to win, especially Milan, but from a quick counter attack Atalanta snatched all three points from an excellent goal by Franco Brienza.
