Manchester City require two victories to retain the Premier League title after despatching relegation-threatened Everton at Goodison Park.
Pep Guardiola's side will be guaranteed their third title in a row with six points from their remaining games against Chelsea, Brighton and Brentford.
But the Toffees were made to pay a heavy price for Mason Holgate's glaring miss when unmarked at the far post, the defender somehow hooking over from a couple of yards.
City were second best up until that point but showcased how clinical they are in front of goal by going to the other end and netted twice in the space of two minutes.
