Despite yesterday's disaster for the Old Trafford faithful in the 2-1 defeat to the Blues, United are too far in front to effect this years title race.
Former Blues striker Niall Quinn has gone on record that his old club will make "spectacular" signings in the summer in response to Manchester United's dominance in this season's title race and Sir Alex will need an even bigger pot to keep pace.
Robin Van Persie's goals have sealed the title after last year's disapointment but when he is not scoring United lack that killer edge.
United have been linked with Spurs Gareth Bale who is talked about as the next Messi and Ronaldo and Roma's Daniele De Rossi one of the best defensive midfielders in the game today. De Rossi has the ability to replace Paul Scholes.
Leighton Banes has long been on the radar and should David Moyes move on from Everton he could also.
As Quinn goes on to say:
"If manager Roberto Mancini is the right man, then I can see him adding one or two to the squad,"
"And I'd say those one or two could be spectacular."
City's second successive victory at United restored a sense of pride to a team which has struggled to match Sir Alex Ferguson's side's consistency this season.
Mancini blamed his club's transfer policy as the reason for why City are lagging so far behind United, despite spending more than £50m in the summer.
Signing this season included Jack Rodwell, Javi Garcia, Matija Nastasic, Scott Sinclair and Maicon but City also again failed to make an impression in the Champions League again this season casting doubt on the Mancini's future at the club.
Quinn added: "It's hard to say Mancini is not the right man. He's brought the title there after all these years.
"It doesn't happen any more and everything is in a rush so it will be interesting to see what line the Manchester City hierarchytake on this. I think it would be harsh [to sack Mancini]."
Game on for next season.
