He is one of the fastest players in the Premier League and confessed it is the biggest part of his game.
Walcott, in an interview with Soccer AM to be shown on Sky Sports 2 today, joked: "I'd be rubbish! It's about touch as well, but pace in the Premier League is massive.
"I'm fairly quick. I'd be up there. There's a lot of pacey players in the Premier League but I'd be right up there definitely."
