After Manchester United's comeback over Juventus, Jose Mourinho went on the pitch and by putting his hand on his ear, he celebrated the 2-1 win.
Juventus defender Leonardo Bonucci politely confronted Mourinho about his celebration.
Later, Mourinho explained the gesture in an interview.
"I didn’t offend anyone at the end," Mourinho said. "I just made a gesture that I wanted to hear them louder.
"I probably shouldn’t have done it, and with a cool head I wouldn’t have done it, but with my family insulted, including my Inter family, I reacted like this."
