After a pass from wing Aurélien Rougerie during the 2003 Rugby World Cup quarter final, France centre Tony Marsh runs past full back Girvan Dempsey and has a clear run to the line. But Ireland centre Brian O'Driscoll tracks back and takes down Marsh with a tackle with textbook technique. Then not only does he make the try saving tackle, he gets back to his feet and competes for the ball and wins Ireland a penalty.
