Manchester City host neighbors United on Monday it what is arguably the biggest match in the history of the Premier League.
A title race that looked all-but over when United took an eight point lead a few weeks ago is now firmly back in the balance. The Red Devils' dramatic 4-4 draw with Everton last week means that the gap at the top of the table is now just three points.
A win for City at the Etihad and, with a superior goal difference, they will likely be just two wins away from securing a first league title in 44 years.
This season's Premier League has seen one of the most intriguing Premier League title races in many a year. City looked imperious early on, before their stuttering form in early Spring derailed their challenge. But another twist in the past few weeks means everything is to play for once again.
