The late goal sparked jubilant scenes on the Chelsea bench and during the celebrations assistant coach Marco Ianni celebrated in front of the former Chelsea man's face.
The action irked the three time Premier League winner, who was restrained by security as he looked to confront Ianni.
Although the Italian later apologised and Mourinho said that he had accepted this, 'Sky Sports' pundit Jamie Redknapp said that he understood the Portuguese's frustration.
"I get it, a little bit. He's goaded by the assistant, and there's no need to get involved there. He's tried to get a rise out of Jose, and sometimes frustration does get the better of you.
"You've just conceded a last-minute equaliser, it hurts. I don't always stick up for him, or feel he conducts himself in the right way, but I get it.
"There's passion involved, it's high-stakes, he's under enormous pressure, it's not ideal when you see a manager react like that, but it's why we love football.
"When you see a last-minute equaliser like that, and the crowd erupts. It's not ideal, but I thought it was a fantastic game."
