"It's the hardest thing that I've ever done from a work perspective," Tom Coyd said, "but also the most rewarding".

Coyd is discussing the unusual challenge he faces as head coach of England's wheelchair rugby league team - he has to manage his younger brother Joe.

By their own admission, the family dynamic can make for some tense moments.

But it worked four years ago as England won the Wheelchair Rugby League World Cup. And on Friday, they hope to win the trophy again by beating great rivals France in the final in Wollongong, Australia (08:45 GMT).

"It's taught me loads about how to be a good brother and loads about how to be a good coach," said Tom, who has been England head coach since 2020. "Hopefully Joe agrees. But it is an interesting dynamic.

"I think there's a reason it doesn't happen very often because it can be really difficult. But in our quirky ways, Joe and I find a way to make it function.

"So it can be something that is a bit strange, but we make it work. And I think the team gets a lot out of it when we do get it right."

Joe was part of the England set-up before his older brother, playing at the 2013 World Cup as a 15-year-old, and now taking part in his fourth tournament.

He has been a key figure in England's run to the final - scoring in every game as they have beaten Wales, the USA, Ireland and Australia - and earning a spot on the eight-strong shortlist in the wheelchair category for the International Rugby League (IRL) Golden Boot award.

"I know I'm in a very lucky and privileged place to to be able to do the things that we get to do alongside my family," Joe said.

"When we don't get it right, it's just because we care, and we've probably got that familiarity with each other, where sometimes we're probably a bit shorter with each other.

"We might say things differently to how I might say them to one of the team-mates or another member of staff because I've grown up alongside Tom.

"But it's great. It's so cool to do it. I don't know another place where we get this opportunity, so we do our best to make the most of it."

Wheelchair rugby league runs through the Coyd family: Father Martin was an England international, played a significant role in the sport's development, and is now the team's general manager as well as a member of the Rugby Football League board.

"He's been out here busy fulfilling his responsibilities as a RFL board member," Tom said.

"But he's been doing that alongside getting oily and repairing wheelchair parts and getting his hands dirty. So he's been in the thick of it and he wouldn't have it any other way.

"I think all of the kind of peaks and troughs that come with competition, he tends to ride those waves very steadily.

"And as someone who's been at the head of the team for over a decade, he sets the standard and drives the culture. He does a good job for us."
