Arsenal were ruthless - Walcott

Arsenal's Theo Walcott says his team were "ruthless" in their 5-2 thrashing of north London rivals Tottenham.

The 23-year-old striker, who scored Arsenal's fifth goal, has particular praise for Spanish midfielder Santi Cazorla who also got on the scoresheet.

As the interview ends, BBC Sport's Jonathan Pearce jokes with Walcott about the newly grown moustache he is sporting.
