His team is magnificent right now, whilst the "Special One" has his mojo back and is looking forward to a "special" game.
Mourinho, asked whether the wish was to go toe-to-toe with Pep Guardiola's team, said: "We are going to try".
The Spaniard reckons United are back to their best and won't be out of the title race even if he beats them at the Etihad.
"Sixy" City were sensational against Shakhtar, and if they play again as they have been doing then their first derby win in four at home is more than likely.
"I lived in Barcelona for many years and know special derbies against Real Madrid, and in Germany against Borussia Dortmund like this weekend - it's special, I know that, but we have to be focused".
The France global was instrumental as United fought back to beat City in last season's corresponding fixture.
"They had a problem for 10 minutes after Cristiano's goal but they were so stable with a lot of commitment, aggressive without the ball".
If City win they will be 12 points ahead of United, but Guardiola, who will be without Kevin De Bruyne, added: "Win or lose they are not out of it". A few weeks ago at Stamford Bridge [against Chelsea], one of the toughest places, they nearly won. It's not possible in November. If they can win in Turin, it shows how strong they are. "They are a big club with a big mentality".
"But United have it themselves, with their history behind them, it's always there. Maybe in March, April but nothing can change at this stage".
