And to get in the Derby mood, we took a look back through the archives at some classic matches between the two rivals.
This one immediately jumped out: City's 3-1 win over United back in 2006.
Goals from Trevor Sinclair and Darius Vassell put City 2-0 up, but Ruud van Nistelrooy pulled a goal back for the visitors.
However, Robbie Fowler's fine strike sealed a superb win for Stuart Pearce's side.
