Sassuolo thus imposed on Inter their only defeats in the championship so far, as they had already won in the first round, in Milan, by 2-1.
It was in the 20th minute that French midfielder Armand Lauriente scored the only goal of the match, contradicting the statistics of the game, in which the Transalpine champion was superior in terms of dominance.
In the complementary stage, the Nerazzurri team were far below their potential, a fact taken advantage of by Sassuolo to save the precious advantage and win the three points.
Despite being the best attack in the championship, with 81 goals, Inter were left blank for the first time in the competition. With nine points to play for, Sassuolo, who hadn't won in six matches, remain last but one in the table, with 29 points, but at least two away from safe spot.
