Callum Wilson is ready to grasp his chance if called upon during England's qualifiers against Bulgaria and Czech Republic.
Harry Kane has firmly established himself as England's leading striker.
But Bournemouth star Wilson insists he will be firing if Gareth Southgate needs him.
"When I get here - train well, wait for my opportunity, be patient," Wilson said. "Harry is a great player.
"I'm not saying I want to kick him out of the team, but with injuries, things that happen along the way, you have to be ready to grasp the opportunity, whether it is one minute, 20 minutes, the opening whistle.
"It's not just thinking: 'Harry is going to play'. Anything could happen and I have to be ready to come on and make a difference. I am fully focused."
