Arsenal had to depend on their 21-year-old forward, Bukayo Saka again to get all three points against a resilient Leeds United side.
The Nigerian got the opener in the 35th minute after some quick exchanges with Martin Odegaard and the sumptuous finish from a tight angle would prove enough to win the game.
Leeds thought they had a penalty late on after Gabriel fell Patrick Bamford in the box, but VAR reviews ruled against that.
Instead of a red card, Gabriel got a yellow and Arsenal got a free kick as the game came to an end.
Saka has now scored 9 goals and assists in 8 games, with today’s goal his 4th in 7 days.
Arsenal have won as many as nine of their opening 10 games to a top-flight campaign for the first time in their history.
Arsenal will stay top of the Premier again regardless of the outcome of the Liverpool vs Manchester City game.
