Milan’s winning streak was ended by Atalanta in the Lombardy Derby, as 16-year-old Gianluigi Donnarumma proved decisive in goal.
The Rossoneri were seeking a fourth consecutive victory and gave M’Baye Niang and Philippe Mexes their first starts of the season, as Jack Bonaventura was suspended against his former club with Mario Balotelli, Alex, Ignazio Abate, Diego Lopez, Jeremy Menez and Andrea Bertolacci injured. The Orobici had won two of the last three visits in this Lombardy Derby, but hadn’t shared the spoils in their last nine meetings with Milan, home and away.
Alejandro Gomez just failed to get on the end of a Mauricio Pinilla assist and there were early timid penalty appeals for a Juraj Kucka nudge on Luca Cigarini. Atalanta lost Boukary Dramè to a muscular problem.
There was a double Milan opportunity, as first Carlos Bacca’s strike was charged down in the box, then a Niang scorpion flick was just beyond the Colombian at the back post.
Niang also burst down the left and Marco Sportiello spilled his angled drive, but nobody took advantage. Mattia De Sciglio risked a second yellow card, so was replaced by 18-year-old Davide Calabria.
After the restart, Sportiello stuck out a foot for a stunning save on Bacca’s header from six yards, but the Colombian had been flagged offside anyway. Niang also tested the goalkeeper after running on to a splendid Andrea Poli low cross-field pass.
Atalanta had a period of pressure, but Pinilla and Maxi Moralez fired wide, while Gomez was booked for simulation after buckling before Calabria made contact in the box.
Milan were being pinned back and had to rely on two sensational saves on a Luca Cigarini downward header and Maxi Moralez strike at the near post, then Maarten De Roon hit the side-netting.
Their 16-year-old goalkeeper Gianluigi Donnarumma needed another great reaction stop moments later on unmarked fellow teenager Alberto Grassi, as it was a siege.
When Milan did break clear and earn a corner, Luiz Adriano’s header was cleared off the line by Cigarini on 79 minutes.
Sinisa Mihajlovic was sent off for dissent and kicking a water bottle in the general direction of the fourth official, as the tension was palpable and Milan were hanging on.
Deep into stoppages the hosts almost struck with a counter-attack, but Cerci hit the side-netting after running on to an Andrea Poli pass.
