We must raise our game - Castaignede

Thomas Castaignede admitted France will need to step up a gear if they are to beat England after toiling to beat Italy 37-12 at the Stade de France.

Italy led 12-8 after an error-ridden first half but France improved after the break and underlined their dominance with tries from Yannick Nyanga, Pieter de Villiers, Aurelien Rougerie and Frederic Michalak.
