Arsenal boss Mikel Arteta believes the 3-1 victory over Tottenham should give his players belief they can challenge at the top this season.
The Gunners were full value for their derby win, gaining revenge for Tottenham's win across north London in May, which effectively condemned their opponents to the Europa League.
They opened the scoring through Partey's fine 25-yard strike and, after Kane scored his 14th goal in 18 north London derbies from the spot, Mikel Arteta's side stepped up after the break.
