The Gunners regained their place at the top of the Premier League table after beating Nottingham Forrest 5-0 at Emirate Stadium.
The match that saw substitute Reiss Nelson score two goals on Sunday put the Gunners ahead of champions Manchester City by 31 points.
This will be the first time the Gunners have won by five goals since 2018.
Gabriel Martinelli opened the scoring in the first five minutes and the game went to halftime with Arsenal with just one goal ahead.
But with Saka out and Reiss Nelson replacing the winger in the second half, Nelson quickly tripled the score in the 49th and 52nd minutes, followed by Thomas Partey’s 57th-minute goal and Martin Odegaard’s 78th-minute finisher.
Striker Gabriel Jesus gave Nelson the assists that led to his goals, while Nelson also provided the last assist of the match for captain Odegaard.
The Gunners are now two points ahead of City, who are second on 29 points.
Nottingham Forrest with the defeat remains in the relegation zone and is in 20th place with nine points.
Although Forrest had a splendid victory last week after beating Liverpool 1-0, they were unable to replicate the shock against the Gunners.
