Mourinho's side played for bragging rights as Paul Pogba scored a brace within the space of three minutes to put United level and Chris Smalling finished off the match to win 3-2.
Last Saturday's result was a complete reversal from the last time they met at Old Trafford, when City emerged victorious, and the visitors' over-zealous celebrations led to tunnel melee.
But unlike London side Tottenham Hotspur, who have played their home games at Wembley this season while they build a successor ground to White Hart Lane, the only venue of comparable size near Old Trafford is local rivals Manchester City's 61 000 Etihad Stadium.
Manchester United stars got their revenge on Manchester City after last weekend's dramatic derby win by cranking up the volume in their dressing-room following the match.
United's victory denied City a record-breaking, earliest ever Premier League title win, and they now need two more victories to guarantee the title.
The report also claims that the United players learned that City players had booked tables in restaurants all over Manchester in preparation for their title glory.
'Booked tables have you? We'll take your f***ing tables, ' was one in every of many snide suggestions directed at Metropolis players in the midst of the second-half.
"If they won they are champions, for all the fans it would be like death".
