France coach Fabien Galthie named an unchanged side on Thursday to host Wales in a potential Six Nations Grand Slam decider this weekend. Second-row Romain Taofifenua kept his place after the loss to England despite Bernard Le Roux's return from injury as the South African-born lock is named as a substitute for Saturday's match at the Stade de France. The visitors can claim a second tournament clean sweep in three years with a win in Paris. Galthie's men need a victory and to beat Scotland in a re-scheduled fixture next Friday to clinch the title for a first time since 2010. The former Test captain stuck with fly-half Matthieu Jalibert and blindside flanker Dylan Cretin in favour of Romain Ntamack and Anthony Jelonch, who are on the substitutes' bench.
