David Beckham, worldwide sporting hero? It wasn't always like that. His sending off, for a petulant kick at Diego Simeone, turned the tide of a brilliant second-round clash between England and Argentina in 1998. A ten-man England held on for penalties but Argentina eventually prevailed. Beckham was vilified in the U.K. with fans booing him everywhere he went. From hero to zero, then back to hero again. Well done, Becks.
