More than a hundred minutes full of decisions for the referee, indeed for the referees, since Valeri was forced out by an injury in the 74th minute to leave the field to the fourth official Chiffi who completes the match.
At 45 'the sparks Lukaku-Ibra after Romagnoli's foul on the Belgian, correct to use the yellow for both to try to dampen the tension, while a heavier hand would perhaps have further exasperated the spirits.
At 58' the second yellow is correct for the Swede who tripped Kolarov on his run, as well as the yellow to Rebic at 63' with his elbow on Barella's face.
Then, Leao makes a foul on Barella. The referee does not see, but then Banti in the VAR room sees the contact. At 96', referee Chiffi sees the naive foul of Meité and calls it. Finally, the warnings for Kessié and Hakimi were right
