Leicester City’s Jamie Vardy latest strike ended Arsenal winning momentum run form in the Premier League after the Londonside’s substitute Eddie Nketiah was sent off late on.
Aubameyang’s 20th league goal of the season looked like heading the host a fourth consecutive win to maintain their late push for a top-four finish.
But the Foxes goalkeeper Kasper Schmeichel made several fine saves to keep Leicester in the game after Aubameyang’s 21st-minute goal, but the visitors came back strongly in the second half.
Arsenal had Eddie Nketiah sent off in the 75th minute for a reckless tackle on James Justin – a decision made after referee Chris Kavanagh viewed a pitch-side monitor.
Leicester then levelled in the 84th minute as Vardy tapped home at the far post after a low cross from Demarai Gray.
