Speaking in the latest issue of Esquire magazine, published on Monday, Walcott said: "Cars are my weak spot but I could spend my money on far worse things like clubbing and casinos.
"I'm aware I'm a role model. I'm not a player who falls over when someone slightly touches me.
"There are players who dive when the opposition is miles away.
"I want to be like Ryan Giggs. Deep down all players want what Giggsy's got - medals, goals, everything but most of all trophies."
