The blood will be boiling Saturday in Manchester and the anxiety at a fever pitch when two long-standing rivals lock horns at City of Manchester Stadium.
Manchester United and Manchester City have been going at each other since the "Manchester Derby" first was contested in 1881. For a long while, especially in the 1990s, United owned the Derby. From May 4, 1991, through Feb. 12, 2011, United went 17-5-8 against City, owning a stranglehold on their rival.
The times they have changed.
Since a 2-1 United win on Feb. 12, 2011, City have become top dog in Manchester, going 10-4-2 against the mighty Red Devils.
So, what happened to flip this historic rivalry? If you ask Roger Bennett of "Men in Blazers," it's a simple tale.
"Manchester Derby is just fascinating proof that in football golden dominance is never a given," Bennett told NBC Sports Bay Area. "The tectonic plates are always shifting. For decades, Manchester United were the kings of the north. Sheikh money, oil money pumped into tiny, puny, self-sabotaging Manchester City and made them a superpower overnight.
"It's really about a team that has been an absolute joke, rising up and absolutely jamming up a team that has humiliated them for decades. It's really about reversal of fortune."

Manchester City currently sit in third place in the table, while City have sunk to sixth.
The Red Devils will look to get back on top Saturday when the two renew their hatred.
