Reiss Nelson's 97th-minute strike won the game for Premier League leaders Arsenal who came from two goals down to beat Bournemouth at the Emirates.
The visitors had gone in front after just 9.11 seconds courtesy of a calm finish from Philip Billing who claimed the record of scoring the second-quickest goal in Premier League history, trailing Shane Long's record of 7.69 seconds.
Marco Sensei then doubled the lead in the second half with a powerful header against the run of play.
However, Arsenal immediately pulled level as Thomas Partey and Ben White found the back of the net to turn the game on its head.
The Gunners in search of a winner huffed and puffed before Nelson slammed in from 25 yards in the seventh minute of stoppage time.
The winger's goal sent electrifying jolts across the Emirates as Arsenal's five-point lead at the top of the table was restored.
This makes it the second time that Arsenal had to wait until stoppage time to win the game at the death.
The first was against Aston Villa in their 4-2 triumph at Villa Park.
