United let a two-goal lead slip to draw with Everton on Sunday just a week after suffering a shock defeat to Wigan, meaning that their cushion at the top has shrunk from eight points to just three.
The Red Devils now face City on Monday in a match which will go a long way in deciding the destination of the Premier League title - but, whilst the game is being billed as a battle of passion and riches, Ferguson insists he sees the rivalry differently.

Ferguson’s claims are somewhat backed up, with Danny Welbeck and to a lesser extent, Tom Cleverley, playing roles in the United first team this season.

A draw would also suit the champions but a City win would place them as the favourites.
