I have to be honest, after the unexpected defeat to Wigan midweek, I was hoping that Norwich City, a team that have been so strong in the league at home this season, would do us a favour and take a point -(if not more) from United's closest rivals.
In reality, they were totally outclassed by a City side that have managed to somehow claw their way back into the title picture.
But is it too little too late for the blue half of Manchester?
Currently, United top the table by 2 points, with a game in hand over City to be played at Old Trafford against Aston Villa tomorrow.
If the Red Devils take all three points, then it means with just four games remaining of the regular season, United will sit five points clear of the Sky Blues.
With a game still to come at the Etihad in two weeks time, anything is possible for City, who (assuming both sides keep a 100 percent record until then) would close the deficit to just two points with two games to play with a win.
However, for them to have any chance of winning the league, they need to maintain the form they are in now and win every match from today until the end of the season.
The 4-0 victory against West Bromwich Albion on Wednesday, followed up by the mammoth 6-1 win today (which for a United fan triggered memories of that awful day in October) has shown to the footballing world that City are not about to lie down and let their bitter rivals walk away with it.
Something that has crucially happened within the last two fixtures is that City's goal difference has once again vastly surpassed that of United's.
This may not seem like a massive deal, but with the two sides so close together at the top, should they finish level on points, it will hand City the league for the first time in over 50 years.
With the Manchester derby excluded, United's run in has been and will continue to be a lot easier than Manchester City's.
As a result, at this stage, United have the edge in the race to first spot, but if they fail to pick up all three points tomorrow against Villa (a team that have given Sir Alex's men trouble in the past), then that could change.
Mancini's boys are finishing the stronger of the two now, with United clinging on narrowly to that top slot.
If today's demolition of Norwich showed nothing else, it proved that City aren't about to back down and submit without a fight.
The season now reaches its most crucial period, as over the next few weeks we will discover which part of Manchester that famous Premier League trophy will call home for the coming year.
