The incident occurred when Fabregas pulled Saelemaekers' shirt, preventing him from getting back into position. Allegri confronted the former Arsenal midfielder and received a red card, while Fabregas escaped without punishment.
Fabregas later apologized for his unsportsmanlike gesture, saying: 'I want to apologize. Today I did something I'm not proud of; I made an unsportsmanlike gesture. I was so excited that I touched the ball; my hands should have stayed at home.'
