Dan Biggar will refuse to accept backhanded compliments as the limit of his powers as he chases “another dimension” to extend still further a glittering Test career.

The Wales fly-half credits his 2018 move to Northampton for expanding his playmaking horizons, but even now, after 13 years at the top, the 30-year-old is far from finished.

What the detractors see as faults, Biggar considers the bedrock of a relentless 83-cap international career.

“He’s been really good, he’s given a lot of confidence in terms of that middle part of my career where I really started to establish myself as the number one.

“There was a lot of confidence towards me from that coaching group in particular. I’ll always be really grateful to Warren.

“I feel I’ve definitely improved since coming to Northampton though, because of the way we play and because of the way the coaches want the players to play and express themselves.

“Chris (Boyd) tells us never to worry about making positive mistakes. In fact he’s saying he’d almost be harder on me from us shutting up shop.

“It’s definitely gutsy from Chris. We know we’ve got the coach’s confidence to express ourselves and be positive, and now we want to go and repay that.”
