Arsenal's Theo Walcott says competition for places is behind the club's strong recent form

The third-placed Gunners have been in great form in the Premier League since January, although their charge stalled on Sunday when they were held 0-0 at home to leaders Chelsea.
That result left them 10 points behind and all-but ended any lingering hopes they had of reeling in the Blues but Walcott believes the strength in depth in the squad means a title challenge next season will be on the cards.
