Dally M medallist Todd Carney has declared halves partner Mitchell Pearce the man to take the Sydney Roosters to NRL grand final glory on Sunday.

With all the expectation on Carney to continue his fairytale comeback with a dominant display against St George Illawarra, the Roosters' five-eighth says Pearce will be the side's linchpin.

"I don't see that I'm the main factor, I think Pearcey's the main factor for us to do well," Carney told AAP on Monday.

"I don't think he'd mind me saying that he's the bloke that will get us across the line.

"He's our go-to man and he sets up all our plays. He's the talker, the leader of our whole structure so I'm confident in Pearcey."

The Roosters' No.7 has been in superb form in the finals series as his side notched wins over the Wests Tigers, Penrith and Gold Coast.

"Last week's game (a 32-6 win over the Titans) was great again from him and the week before that (34-12 over the Panthers) he was outstanding," Carney said.

"You can tell in him again this week that he's up for a big one."

Carney is on the verge of completing one of the NRL's greatest Cindarella stories.

Banished from the league for 12 months as he got his off-field act together, few foresaw his rise to the absolute elite of the NRL so quickly.

But Roosters skipper Braith Anasta was one of them.

"He's always been a good player but he had potential to be a great player if he just got everything right, and he did," Anasta said.

"In the pre-season we were seeing the way that he was moving and the way that he was training and we're thinking, 'this guy's something special, he's going to be good for us this year'.

"We didn't know how good. We didn't probably expect him to be as good as he (has been).

"There's a lot of instinctive players but they don't have the speed and the footwork of him."

Carney is aware he is at the peak of his powers in a Roosters side bidding to be the first since Western Suburbs in 1934 to go from wooden-spooners to premiers.

"Some say (it's) a fairytale," he said.

"It would cap off the best year of my life and I don't think there'll be a better year after this year.

"It would mean a lot just for this group of boys to win it and I'll do anything in my power to try and get that win."

Built on the combination of Carney and Pearce, the Roosters' flair would seem the perfect weapon against the NRL's stingiest defence at ANZ Stadium.

But Carney is wary of the pressure the Dragons' big men exerted in a round seven 28-6 victory and a brutal 19-12 win at the SCG two months ago.

"We can score points but it's easier said than done," he said.

"The Dragons don't give much away.

"Our main focus is we've just got to defend as well as they do to beat them because they're a fair attacking side too."
