But it's not all sunshine and roses for Arsenal. Star player Bukayo Saka continues to struggle with ongoing injury problems.
The winger was due to start the match, but was injured in the warm-up and did not play at all.
Noni Madueke then stepped into the starting eleven and immediately repaid the faith with a perfect pass to Martin Zubimendi, who headed in to make it 1–0.
Ten minutes later, Madueke took a corner that Leeds goalkeeper Karl Darlow diverted into his own net. It was Arsenal's thirteenth corner goal in the Premier League this season.
In the second half, Viktor Gyökeres made it 3–0 when he pushed forward and tucked in a cross from Gabriel Martinelli. It was the Swede's third goal in four games, and he had scored in two consecutive Champions League matches.
Gabriel Jesus made it 4–0 with five minutes left to play.
Arsenal are steaming ahead in the league, seven points clear of Manchester City, who have played one fewer game.
Swedish national team defender Gabriel Gudmundsson was back from injury and played the full match for Leeds.
