South Sydney's prospects for 2027 have drawn attention since Payne Haas joined the club in February.
Pundits have described Wayne Bennett's side as a genuine contender for its 22nd premiership.
The game's premier prop helped Brisbane end its premiership drought in 2025; now he wants a title with the club he supported growing up.
The Rabbitohs have not won a premiership in 14 years.
Haas avoided claiming his arrival alone would take South Sydney to the next level.
He said he would not have joined unless he believed the squad could challenge for a title.
"Yeah, for sure. You look at the players we've got. I wouldn't come here if I didn't think that," Haas told reporters at the club's headquarters on Monday morning.
