The Reds' extraordinary 4-4 draw at home to Everton coupled with Manchester City's 2-0 win at Wolves has seen the gap at the top reduced to just three points.
United remain in pole position, but know defeat in Monday night's Manchester derby would hand the initiative to City.
Here we cast an eye over each team's remaining fixtures...
Mon 20 Apr - City v United (20:00)
The biggest Manchester derby ever? It’s a label that’s been attached to plenty of United-City fixtures in recent years but this time it's actually true. The Blues' home record is seriously impressive... but so is the Reds' away form and we did win there in the FA Cup in January. Whatever happens, we must ensure we avoid defeat.
