Marouane Fellaini scored in injury time to secure United's progression to the knockout stages.
And speaking after the game, Mourinho took a shot at his critics by listing his European record.
"Let me send a message to my lovers and let me say that I've played Champions League for 14 years and I've qualified 14 times," the Portuguese told his post-match press conference.
"The two years where I didn't play in the Champions League, I won the Europa League twice.
"So in 16 years, 14 times I qualify and twice I play Europa League and I won. So just curiosity for my lovers and the lovers of the stats."
