At the time Arsenal had not lost for 30 games, so their surprise loss at Everton helped Rooney steal the headlines.
He hadn't even signed his first big-money professional contract at that point, because he wasn't old enough!
Even though he'd only played one season it was enough to win Rooney his first major award, the BBC Young Sports Personality of the Year for 2002.
Later that season he became the youngest-ever England international in a friendly against Australia.
The following season he scored his first international goal against Macedonia, becoming the youngest player ever to score for England, aged 17 and 317 days.
