Arsenal moved eight points clear at the top of the Premier League with a 2-0 win over Tottenham Hotspur in the North London derby on Sunday.
A dominant first-half display from the visitors did the damage as Hugo Lloris palmed Bukayo Saka's cross into his own net before Martin Odegaard's long-range effort found the bottom corner.
Aaron Ramsdale denied Spurs their customary comeback from two goals down this season after the break with saves from Harry Kane and Ryan Sessegnon.
A fourth home defeat in five league games leaves Tottenham five points adrift of the top four.
The game ended on a sour note as Ramsdale was involved in an altercation with Spurs substitute Richarlison and was then kicked by a home supporter as he went to collect his water bottle from behind the goal.
