Or casually whistle up gifted youngsters such as Fabien Brau-Boirie, Émilien Gailleton and Gaël Dréan who all look instantly to the manner born. When you factor in the squad’s collective ability with and without the ball – to date France have scored the most tries, 18, and conceded the fewest, five – the future looks dazzlingly bright.
