The city of Manchester is a pretty atmospheric place to be right now.
Fans of both legendary clubs aren't really sure which way this match will turn out. Local rivalries, mainly deriving from which part of town you come from really come to the fore.
For City fans, it's a new dawn, as boosted by Arab megabucks they attempt to overtake their red rivals.
United fans point out that the Dog and Partridge has been demolished and rebuilt, so anything is possible.
Still smarting from the last day of the 1968 season when City won the Championship by winning 4-3 away to Newcastle as United succumbed to an uncharacteristic home defeat to little fancied Sunderland, one elderly United fan told us:
"I cried me eyes out. Losing the Championship was bad enough, but losing it to City was the ultimate nightmare. They were as good as us back then, with Mike Doyle, Franny Lee, Tra la la la Summerbee, Colin Bell, and that mad woman who used to sit behind the goal ringing that bloody bell!
"They've had the upper hand lately in head to heads, but in fairness their respect on the Munich anniversary was impeccable - apart from the dickheads outside who set the fireworks off in the minute's silence. I think we'll turn em over this time, Adebayor, Robinho and all."
We also spoke to a parka wearing City fan on Oldham Road who looked a little like Liam Gallagher out of Oasis.
"Do you think City will get a result tomorrow?" we asked.
"Yeah mate. No probs. Fuckin' sorted like innit."
More as we get it.
Update:
Final score Manchester United 4 Manchester City 3
The most exciting Manchester Derby in years ended up with a United victory in a fantastic game.
Ironically, Michael Owen (ex Liverpool) netting the winner in time added on purgatory.
Much rejoicing in some quarters.
But probably not in the Mark Hughes residence this evening.
