Wales host France at the newly named Principality Stadium in what could be the defining clash of this year's Six Nations. Two weeks on from their grueling victory over Ireland, France will have yet another huge test against a strong Welsh side. France were expected to go through a season of transition, yet if they can claim victory here they would be in pole position to win a Grand Slam. Wales, currently third in the standings will know that they will need to win if they're to have a realistic chance of winning the Championship. (Kick Off: 8.05pm)
