'I'll be ready': Teen freak's huge warning to NRL rivals

Hyped teenager Joseph Suaalii has sent a warning to NRL rivals claiming he would be ready to play this year if an exemption is made.

The Roosters prospect took the field on the weekend to make his senior debut in a NSW Cup trial for North Sydney in which he scored two tries at right centre in his first game in 18 months.

Speaking at King's School on Monday afternoon, Suaalii said he would be ready if the NRL made an exemption and allowed him to play at his age.

"Yeah, I'd be ready. As an athlete you kind of have to be, you want to be ready," he said to reporters.

"I've got a lot of stuff that I need to work on before I get to that point but if I do get a chance to make my debut, it would be a childhood dream to go and play for the Roosters and make my NRL debut."

The Roosters have lobbied for the NRL to let Suaalii take part in the competition before his 18th birthday, a request the NRL is weighing-up.

Should the NRL grant the exemption, it's likely Suaalii could make his debut mid-season.

Suaalii showed glimpses of extraordinary talent

Suaalii showed why his signature was the so sought after but the 18th month lay-off saw him taken off the field with a cramp.

But the two tries at just 17-years-old showed just why the Roosters fought to lure the teen to Bondi from under the nose of South Sydney and Australian rugby.

"(Robinson has) been a big help since I've been here, I've learnt a lot from him," Suaalii added.

"As a junior, I played a bit of everywhere. I don't have a favourite position in the outside backs.

"Centres felt good, but I'd be happy wherever they put me."

NRL veteran and Roosters winger was in shock at how powerful the 196cm-tall high-schooler is in the gym.

"He's a really good kid, really humble and ready to work hard," Morris said.

"He's a really good mover on the field.

"He's quite strong in the gym as well.

"He is only young, but he's definitely not out of place when we're in the gym throwing weights around or in the wrestling room.

"Even in the field doing fitness and speed, he's certainly handled himself this pre-season."
