Walcott feels he has the ability to take games by the scruff of the neck.
"I would like to be more aggressive in matches and the manager has said that to me. Not by kicking people but by running at players. That's the main improvement I need to make. When I play my best football, I am aggressive and not afraid of getting hurt. I am not afraid to put a foot in and that's what he wants," he told Standard Sport.
