Manchester City are one win away from being confirmed as Premier League champions for the fifth time.
The rearrangement of the fixture will be announced in due course. But City can now win the title on Saturday 8 May, when they host Chelsea.
Victory would secure the PL Trophy for Pep Guardiola's side, but the visiting Blues knocked City out of the FA Cup last month and are unbeaten in seven away league matches since Thomas Tuchel's appointment as head coach.
Man Utd's next Premier League match is at Aston Villa on Sunday 9 May, and they must better Man City's result to stay in the hunt.
If City lose to Chelsea, United would need to avoid defeat themselves at Villa Park to keep the race alive.
A draw for the leaders at the Etihad Stadium would give the Red Devils a must-win match in the Midlands.
