The Red Devils scored twice in the final five minutes to pull off an unlikely win against the Serie A giants in Italy.
Mourinho would have no doubt been peeved by news on Wednesday afternoon that the FA were appealing a ruling that found him not guilty of using abusive language after a victory against Newcastle in October.
The 55-year-old admits he said f**k yeah in Portuguese into a camera after Uniteds win but claims that the context was key and that he did not aim the words at anyone in particular.
Mourinho embroiled himself in more trouble after the win against Juventus when he cupped his ears to the home support.

The United boss was asked about the incident after the game and asked a reporter if she had heard what the supporters had been screaming at former Inter Milan boss Mourinho throughout the game.
Mourinho asked her: Do you understand Italian? and when she replied no he responded: Ask the FA, they will translate for you.
