Arsenal were left to rue a missed opportunity to move to within four points of Premier League leaders Liverpool after being held by Fulham at Craven Cottage.
Bukayo Saka thought he had given the Gunners all three points when he headed in from close range two minutes from time in west London.
But the goal was chalked off following a VAR review, which found Gabriel Martinelli was offside during the build-up.
Raul Jimenez had given Fulham the lead in the first half when he slotted past David Raya from a tight angle for his sixth goal of the season.
Arsenal mustered just a single shot on target during the first half, with former Arsenal goalkeeper Bernd Leno saving well from Saka.
The Gunners were level within six minutes of the second half when William Saliba converted after a well worked corner kick routine that saw Kai Havertz set-up the Frenchman.
Arsenal dominated for the remainder of the game and thought they had found a winner through Saka, only for the VAR to intervene to ensure Fulham earned a point.
The draw leaves Arsenal second, six points behind Liverpool having played a game more.
