Kai Havertz and Ben White scored twice as Arsenal thrashed Chelsea 5-0 on Tuesday to surge ahead in the Premier League title race and ramp up the pressure on Liverpool and Manchester City.
Leandro Trossard was also on target in a record win over Chelsea for the Gunners, who move three points clear of Liverpool and four of Manchester City.
The destiny of the title remains in City's hands as the defending champions have two games in hand.
Liverpool have also played one fewer game than Arsenal and are in action at Everton in the Merseyside derby on Wednesday.
However, Mikel Arteta's men's goal difference advantage now looks unassailable should it become decisive in the title race.
