Not for the first time in his managerial career, Mourinho was dismissed by referee Antonio Rapuano in the 89th minute after he was deemed to have taken his protests on a number of decisions too far.
With Roma down by a goal at the time, Andrea Belotti missed a penalty moments after Mourinho's dismissal before substitute Nemanja Matic ensured a share of the spoils with a late equaliser.
The result ensured Roma will head into the World Cup break seventh on the Serie A standings with just one win in their last five games.
"It was the right decision – my words to the referee deserved a red card," he told DAZN. "I spoke to him after and apologised, but I don’t want to talk about his performance.
"I was humble enough to apologise, but I will leave his performance and the hypothetical influence on the match to you.
"I don't want to talk about what we said, that was private. My words deserved a red card, but I will not judge the referee's performance."
On a brighter note for Roma and Mourinho, Paulo Dybala returned after a month-long absence through injury and the former Chelsea boss highlighted how the Argentine's services have been missed.
"There are two games tonight – one until the 70th minute and one after," Mourinho said. "Until the 70th, Roma fans wanted to just go home.
"But in the final 20 minutes we created more, perhaps more than we have done in the last four or five games. Why? Easy, because Dybala came on.
"When you have a player like Paulo and he doesn't play, it's different. How many extra points would we have now if Dybala hadn't been injured?
"The break is coming up, it will be the right moment for certain players to look at themselves and try a little self-criticism.
"Despite all these problems, we are a united group. A team that misses a penalty at the 92nd minute is usually dead, but not us, we kept going."
