Arsenal, who were in good form before the international break, visit north London rivals Tottenham Hotspur in one of the capital's most hotly contested derby clashes this weekend.

Tottenham hope to recall England winger Aaron Lennon for the first time since he had knee surgery in May and could also have striker Darren Bent back after a thigh injury.
