Sam Warburton: 'George North one of the best in the world'

Wales captain Sam Warburton has hailed winger George North as "one of the best players in the world" ahead of the upcoming Rugby World Cup.

North has been a doubt to make the tournament having suffered a spate of concussions earlier this year, resulting in him missing the final 10 weeks of last season.

However, the Northampton man returned to full training today, and Warburton insists that he was always confident North would make the squad.

"He has been training really well from day one. Physically he is a freak and I never thought he was going to miss the World Cup," Warburton told reporters.

"He is one of our players with X-factor and, in my opinion, one of the best players in the world.

"Athletically he is in fantastic shape now and I am sure we will see the best of George over the next few months."

Wales open up their World Cup campaign on home soil against Uruguay on September 20.
