United are more than capable of scoring but they are also unlikely to keep a clean sheet, having prevented only Burnley from finding their net in six away matches this season.
Asked if he felt United were operating on a fair playing field ahead of the derby, Mourinho said: "It's hard for me to answer because I focus on my job, I focus on the four lines".
'In a positive way is easy to feel a team that does not give up, always find a way to fight back sometimes changing results, sometimes not but we are a team that has that collective spirit to fight back but is not always possible.
United are nine points behind the Premier League leaders after 11 matches as they travel to the Etihad Stadium.
"It's a fantastic victory for us, a victory that is not just about the points we lost at home but the feeling of how well we played", said Mourinho.
"It leaves a bitter taste in the mouth, but we can´t win all the time".
"We want to play well, we want to go to every stadium and do that, no matter which team we are against".
"I wouldn't do that gesture again, but I don't think I offended anyone and at the time it seemed like the appropriate response to those who had insulted all my family, apart from my Inter one too".
Allegations of financial impropriety off the field couldn't derail Manchester City moving to the brink of the Champions League last 16 as Gabriel Jesus scored a hat-trick in a 6-0 thrashing of Shakhtar Donetsk on Wednesday. "I don't think it's the way to look at the match".
"We have to just think about the match, it is hard enough by an isolated event. But I respect Juventus, their players, the manager, the quality they have".
"If we keep conceding goals before the opponent, there will arrive the day where we can not come back", he said.
"We know that (Juventus) is a big team and, to be honest, when they scored a goal, we had nothing to lose".
"I was insulted for 90 minutes".
"We have to defend deep, well, strong, defend the crosses because they are so strong, avoid set pieces because they are huge, by far better than us. Which, I have to say against Juventus, it happened".
