Arsenal edged a heated north London derby on Sunday afternoon thanks to a second half header from Gabriel.
In what was a heated first half that saw the most yellow cards shown in the opening 45 minutes of any Premier League game ever, the players clashed after Jurrien Timber narrowly avoided a red card.
It was tight in the second half too, with Gabriel heading in Bukayo Saka's corner for the only goal of the game.
Arsenal went second with the win, while Tottenham remain in the bottom half after a difficult start to the campaign.
