STUART Lancaster has no qualms about picking Anthony Watson on the right wing for Saturday's QBE International against South Africa and believes he is ready for his first Test start.

Watson made his debut as a second-half replacement in the 24-21 loss to New Zealand and starts against the Springboks at Twickenham in place of Bath team-mate Semesa Rokoduguni, who has been ruled out by a thigh injury.

The 20-year-old Bath wing's inclusion is head coach Lancaster's only change to the England team beaten by the All Blacks and his place on the bench is taken by Harlequins' Marland Yarde in the only other adjustment to the 23.

"Anthony has been pushing hard for a while," said Lancaster. "He has got all the physical attributes you need. He's tall, good in the air, has pace and good footwork. Now his experience will be tested.

"His chance has come because of the injury to Roko, and his form for Bath this season, but also because of the conversation I had with him before the New Zealand match.

"It would have a big step for a 20-year-old to go into a match against the world champions from the start but what came across was how confident he was and how prepared he was. He is definitely ready."
