The team from Bergamo put the Rossonerri under the sword in this one. Well taken chances by Romero and Zapata either side of a penalty by Ilicic handed Milan only their second defeat of the season. The first by Christian Romero taking advantage of lax defending by defender Kalulu to score from close range with a diving header. The second by Ilicic was a clear penalty in my opinion. Kessie was protesting all about nothing as replays showed he elbowed the opponent. Donnarruma unlucky to see the effort go under him.Zlatan had a match to forget missing a sitter when it was easy to score than miss. He was overshadowed by Colombian Zapata whose menacing presence constantly troubled the shacky backline of Dane Kjaer and Frenchman Kalulu. Zapata putting the gloss on a 5 start performance all round for Atalanta on 77 minutes. He side footed into the net after being put through by Romero making it look easy against the side who are leading the league. They are fortunate to still be top, Inter dropping two points at Udinese in a stalement. Milan lead their city rivals now by two points.
