RBS 6 Nations

Les Bleus have been overlooked as title contenders in many quarters but an impressive 21-16 victory over Wales in Paris has seen them emerge as dark horses for the title.
 
Marc Lievremont has made three personnel changes to the side that beat Wales so impressively in the last round.
 
Lock Jerome Thion and prop Lionel Faure return to a beefed-up pack which includes Sebastien Chabal in his preferred role in the back row, while Francois Trinh-Duc starts at fly-half.
 
England have responded in kind, with powerful London Wasps lock Simon Shaw awarded his first England start since last year's championship.
 
Leicester's athletic flanker Tom Croft has replaced James Haskell in a bid to counter France's lineout agility, while Ugo Monye has replaced the out-of-sorts Paul Sackey on the wing.
 
England return to Twickenham desperate to end the indisicpline which has seen them concede 42 penalties and have six players sin-binned so far this championship.
 
That poor disciplinary record was a major factor in England's defeats to Wales (23-15) and Ireland (14-13), where a raft of penalties either conceded points of valuable momentum to the opposition.
 
Johnson has brought leading referees Wayne Barnes and Andrew Small into camp over the last fortnight to try and hammer home the message.
 
England boast an encouraging home record against France and they have won both their last two meetings with Les Bleus - in last year's RBS 6 Nations and in the 2007 World Cup semi-finals.
