Warburton upbeat on Six Nations

Captain Sam Warburton says Wales are upbeat about defending their Six Nations title despite poor results at international and regional level. Wales enter the championship on the back of seven straight defeats and none of the regions reached the Heineken Cup knockout stages. Wales have not won since beating the Barbarians 30-21 in June . "[We are] Grand Slam champions and that's how we are going to approach the campaign," said Warburton. The Cardiff Blues open-side flanker understds that there is a depressed air about Welsh rugby but insists that it has not entered the Wales camp, despite four defeats to Australia and reversals against Argentina, Samoa and New Zealand.
