A very disappointing result. It was Milan's home match. Moreover Sassuolo is not a strong team. Even if it was an away match, this match should have been won by Milan. Milan lost at home, and conceded 3 goals. If they want to win the title, they have to play carefully in all the matches. Points cannot be lost against a weaker team.
Unexpected result from AC Milan. They had a very bad match from both result and performance on field.
I think with team like Milan, such defeats can make them derailing from their win streak and if they can not resolve it to come back too soon, they might fall into a downside in this season.
I honestly think that Milan got frustrated saying that how well their opponent was playing. Even I did not think that Sassuolo would ever beat Milan in that match in any way. And moreover, they scored three goals. And to make things worse the Milan goal scorer Romagnoli, who scored the only goal for Milan in the 27th minute, was red-carded on the 77th minute. Really horrible performance from Milan I have to say.
Romagnoli lost his position since the last season and I think his performance is affected by less real matches he played recent months. He used to be a captain and most important defender of Milan but things changed. This bad performance will put Romagnoli into another bad period. He must be very strong to come back but I believe in him.
Why? Because he had his debut when he was very young in AS Roma but he did not join into the main squad of Roma. He left and played in a few other clubs. Slowly he built up his position in AC Milan and he is still young enough to come back. What he is witnessing is not worst in his career.
