Gunners aim to resolve defensive errors

ASHLEY COLE has said size does matter as Arsenal started to address the defensive failings at set-pieces which threaten to undermine their title bid.

Sol Campbell insists the title race remains wide open despite Chelsea's five-point lead but he and Cole still know the Gunners must improve their defending at corners and free-kicks.

Half of the goals conceded by Arsenal so far in the league have come from set-pieces, and their goals-against tally of 22 from 17 games is already just four short of last season's overall total.
