He is especially famous for a bending 40-yard free kick against France in the inaugural match of Tournoi de France 1997 on 3 June 1997. The ball curled so much that the ball boy ten yards to the right ducked instinctively, thinking that the ball would hit him. Instead, it curled back on target, much to the surprise of goalkeeper Fabien Barthez, who just stood in place. This particular attempt is considered to be the greatest free kick of all time. In 2010, a team of French scientists produced a paper explaining the trajectory of the ball.
