AS Roma was lucky because their opponent during the match received a red card in the 63rd minute. So AS Roma took advantage of this moment to corner Sassuolo's defense and win easily. If Sassuolo didn't get a red card, then AS Roma's chances of winning were very small. The difference in points between the third and first positions is quite far away, and AS Roma must keep trying hard to win the third position.
Sassuolo took the lead in the first half and in the second half, precisely in the 63rd minute, Sassuolo had to lose 1 player and Sassuolo was forced to play with 10 players then suddenly lost their balance.
