Leigh Halfpenny - a humble hero who never knew how good he was

It's not often BBC Radio 1 come to the Scrum V desk looking for help lining up a guest.

But news of Leigh Halfpenny's retirement at the end of this season has attracted widespread, and deserved, attention and acclaim.

Second in the 2013 BBC Sports Personality of the Year behind Wimbledon champion Andy Murray, he was a British and Irish Lion whose appeal stretched way beyond the traditional image of a rugby player - youthful, almost boyband in look, he had a reach few in the game ever manage.

Halfpenny would have baulked at that description.

No ego. No noise. Just a quiet, consistent excellence that defined his 20-year career. Now fittingly, a quiet confirmation that he will retire at the end of the season aged 37.

Because this is more than just another retirement.

Best defensive full-back the game has ever seen

Back in 2008, a Wales Under-20s side went deep into the Junior World Championship and hinted at what was coming. Sam Warburton, Justin Tipuric, Dan Biggar, Rhys Webb, Jonathan Davies and Halfpenny were in that side.

Grand Slams, titles and World Cup semi-finals. For a time, the best team in the world.

One by one, they've gone. Halfpenny is the last.

The numbers are strong. Some 101 caps, 801 points - third behind Neil Jenkins and Stephen Jones - but they don't quite explain him.

He was unassuming, almost bashful, and the last person looking for credit.

Yet the one everyone trusted.

Nobody has a bad word to say about him. In this game, that's rare.

His former Wales coach Warren Gatland called him the best defensive full-back the game has seen. At his peak, especially with the British & Irish Lions in 2013, he was probably the best full-back. Full stop.

He was more Ronaldo and Nadal

What set Halfpenny apart was the work.

A perfectionist, obsessive about detail, and as committed to his craft as anyone in the professional era.

That started early, kicking balls for hours in Gorseinon, and he never really changed.

Injuries disrupted his career, sometimes cruelly. A missed World Cup, long absences, even the game of his 100th cap against Canada in 2021 ended with a serious knee injury in the first minute.

But he got everything out of his body.

If Antoine Dupont is the game's natural talent - the rugby equivalent of Lionel Messi or Roger Federer - Halfpenny was the other side of it.

He was more Cristiano Ronaldo or Rafael Nadal. Not in build, but in method, everything earned, in a frame many thought too small for this level.

When he played, he delivered. Technically excellent, positionally outstanding and ice-cold from the kicking tee.
