Walcott accepts his delivery isn't a strong part of his game.
He told the Mail on Sunday: "The practice has helped, as well as watching David Beckham (crossing) in training. We're different players: he doesn't like to beat players, he just likes to get the ball in the box.
"It's difficult when you're running at such pace to cross it and, if there's no-one in there . . . at times at Arsenal we don't always get players in there, although with Marouane Chamakh up front it has changed. Hopefully people are starting to realise a bit more it's not just bad delivery at times but the need to pull into space and make sure someone is there.
"On goals, I want to get to double figures, my target is between 15- 20 and I'm on seven, so I should hopefully get there.
