Mikel Arteta insists Arsenal's euphoric win over Tottenham will fire his title-chasers with belief after a gutsy win in the North London Derby.
Gabriel Magalhaes headed home the winner to secure victory for the Gunners to maintain their unbeaten start to the season.
Arsenal were without key midfielders Martin Odegaard, who is suffering with an ankle injury, and Declan Rice, who missed the game through suspension.
And the fact the Gunners were able to grab three points without key personnel bodes well for his side's attempts to dethrone Manchester City.
