The Canberra Raider's kids have made sure of that.

Keary tore a dreadlock from Melbourne Storm second-rower Felise Kaufusi's head in the Roosters' preliminary final win last week - just before he sent a swinging arm into his face.

But Soliola, as the Raider with the biggest hair, isn't worried if the playmaker decides to make him a target in the NRL grand final.

His young family has been preparing him for that moment since the day they were born.

"We'll be right. I'll be fine. I've got no dramas with that. The kids pull my hair enough as it is," Soliola joked.

"I've had a lot of training for that. It'll just be water off a duck's back, probably doing me a favour."

Soliola also said the Raiders have been preparing all season for the decider at Sydney Olympic Park on Sunday.

From the very first day of pre-season until 11 months later, it's all been building to this.

That's included making sure the young guns throughout the team are ready as well.

"We trained for this week since day one. If you haven't prepared for this week I'm not too sure what you're practicing for to be honest, because - especially that period from November 1 to Christmas - a lot of our talk was preparing for this day, when it gets to this week," Soliola said.

"In terms of mentality and attitude and standards that's what we train for. It's not just us senior players or the top 17.

"We're talking about everyone in the top 30. Because you just never know, like Emre [Guler] for example.

"He's in and out of the first grade, but now we've had to call on him for these last, most-important games.

"We've practiced with him. We've practiced with Corey [Horsburgh].

"We've been under that much duress, we've ran that many 800 metres it's not funny.

"It's just all come down to this one 80-minute performance that we've all worked hard for."

Soliola will be part of the Raiders pack going up against Roosters enforcer Jared Waerea-Hargreaves.

What did he expect from the New Zealand international after a week off due to suspension?

"A lot of pain and a lot of hurt I suppose, but that's good because guys like him and Sam Burgess, [Addin] Fonua-Blake, those enforcers, they make you play the best you can because you have to prepare," Soliola said.

"If you're down one per cent against those guys it's going to be a rough day in the office.

"But we're lucky we've got our own guy in that as well, in the face of Josh Papalii.

"He's been a huge lift for us this year and he deserves every accolade he gets.

"I actually like the balance of the Roosters' forward pack. Jared coming back just adds that extra aggression to their team."
