Sherratt pointed to Winnett’s workload during the past 12 months.

“Because he has been going from week to week, while he has not been injured, he has been picking up little niggles,” said Sherratt.

“I think he played 27 games last year. A year before that he would have had about a dozen games that were mixed with Cardiff RFC, a couple for us and some Wales Under-20s matches.

“So his short-term development has been quite stratospheric.

“It has been a massive straight line, up from Cardiff RFC, to a couple of regional appearances, to pretty much starting every game for Wales and playing very well.”
