Max Dowman became the youngest scorer in Premier League history as his late goal helped Arsenal to edge past Everton and move 10 points clear at the top.
It looked as though Everton were going to frustrate the Gunners and battle to a well-earned draw before Arsenal substitute Viktor Gyokeres tapped home in the 89th minute after Jordan Pickford completely misjudged a cross.
The visitors then threw everyone forward as they hunted an equaliser with a stoppage-time corner.
However, with Pickford stranded upfield, Dowman beat two defenders before racing away to roll the ball into the empty net and spark wild scenes inside Emirates Stadium.
Dowman is now the Premier League’s youngest goalscorer (aged 16 years and 73 days), breaking a record set by Everton’s James Vaughan (16y 270d) in 2005.
The Toffees played well and twice went close to opening the scoring in the first half, with Dwight McNeil denied by an acrobatic block by Riccardo Calafiori before the winger hit the post with a curling effort from the edge of the area.
The Gunners thought they should have been awarded a penalty in the first half when Kai Havertz tangled with Michael Keane in the area but in the end it did not matter as Arsenal found a way to win with their late goals.
Arsenal are now 10 points clear of second-placed Manchester City having played two games more. Pep Guardiola’s side face West Ham at London Stadium later (20:00 GMT kick-off).
