LONDON: Arsenal maintained their early-season 100pc Premier League record by winning 1-0 away to Crystal Palace in the latest London derby.

A penalty converted by captain Martin Odegaard was the difference between the teams with Arsenal down to 10 men in the closing stages after the expulsion of Takehiro Tomiyasu for a second yellow card.

The lone goal came after 53 minutes. Eddie Nketiah was brought down by Sam Johnstone after Gabriel Martinelli’s quickly taken free-kick and Odegaard sent the goalkeeper the wrong way from the spot.

At that stage Mikel Arteta’s side looked comfortable, but they were left hanging on after left-back Tomiyasu was shown a red card for two bookings.

The first yellow was for taking too long over a throw-in and the second was awarded for a minor foul on Jordan Ayew in midfield.

Palace applied late pressure, with Tyrick Mitchell drilling over in injury time, but the Gunners, who hit the post through Nketiah in the first half, deserved their victory.

Arsenal join Brighton and Manchester City on six points from two games, while Palace failed to build on their opening-day win at Sheffield United.
