Arsenal defeated Bournemouth 3-0 in Saturday’s early kick-off, to open a four-point lead ahead of Manchester City at the Premier League summit.
Bukayo Saka gave the hosts a deserved lead from the penalty spot after Kai Havertz was brought down in the area.
There were no further goals in the first half, as the Gunners went in ahead at the interval.
Leandro Trossard swept home their second following a spell of Bournemouth pressure after the break.
The visitors had a goal controversially ruled out after that, with VAR upholding referee David Coote’s decision to penalise Dominic Solanke for a foul on David Raya.
Declan Rice added a stoppage-time third to put the result beyond doubt.
The victory, Arsenal’s fourth in a row, maintains their title charge and puts the pressure back on Manchester City as they host Wolves in the 5.30pm kick-off.
