The theory a family’s youngest sibling often becomes its best footballer might be set to face its biggest test yet.

Troy Warner — the brother of Sydney superstar Chad and his fellow Swan Corey — has been among Western Australia’s best performers in the ongoing under-16 national championships.

A midfielder who has also spent some time across the half-forward line, Warner won a team-high 25 disposals as his side beat South Australia by 12 points in their first game last month and backed up with another 27 in another 27-point win over Victoria Metro on Tuesday.

WA coach Michael Glassborow said he had no doubt the youngest Warner brother had the talent and drive to emerge as a star in his own right.

“He’s been playing his role really well — but in our side, everyone plays their role, which makes it easy for him to be able to go and do what he wants to do,” Glassborow told The West Australian.

“He’s super clean and he runs hard. He’s got a really good ability to be able to break tackles and get the ball to the outside for us.

“At this age, Troy probably has a little bit more speed and agility, which might have come a little bit later for Chad.

“They’re very similar, but probably very different at the same time.

“That’s going to be the challenge — we want Troy to have his own identity and not always be compared to someone else. We’re really big on that in our program.”

If WA defeat Victoria Country in their final game of the championships on the Gold Coast on Friday, they will secure what would be their first title since 2017.

That side featured 11 players who went on to become AFL draftees, including Fremantle superstar Luke Jackson, his 2021 Melbourne premiership teammate Trent Rivers and West Coast midfielder Deven Robertson.

Although the draft is at least two more years away for this year’s crop of under-16s, Glassborrow said he was confident it could prove similarly fruitful.

“There’s probably 12 or 13 guys that the recruiters would have taken some notice of over the last couple of games, which is really exciting for WA footy,” he said.

“I think they’re only going to get better over the next 12 to 18 months, when they grow a little bit more.

“We’ve given ourselves a good opportunity to do something pretty cool as a group.”

WA could still claim the title in defeat, pending the result of a game between South Australia and Victoria Metro earlier in the day.
