Former St Helens captain Paul Sculthorpe says the club's new Langtree Park stadium will be key to attracting new supporters.
The 34-year-old hopes fans from outside the town will come to watch matches.
"That's the aim of the club, to widen the fan base," Sculthorpe told BBC Radio Merseyside.
"We've had a lot of success in Liverpool [in attracting fans] in recent years and hopefully this place will attract even more."
Sculthorpe, who retired from rugby in 2008, spent 11 years playing for St Helens after joining the club from Warrington in 1997.
He is delighted that the club's vision of a new stadium - which will be ready in time for the new Super League season - is nearing completion, but he still has great memories of playing at their old home of 120 years, Knowsley Road.
"The club's moved forward with the times, but there was no better place to play than at Knowsley Road," the former Great Britain international continued.
"Certainly, in front of a full house there the atmosphere was electric and hopefully we can move that over to Langtree Park.
"Knowsley Road was worth a 10-point start before any game with the crowd behind you. This new place with the terracing will keep that atmosphere and it's quite closed and compact.
"The fans have certainly bought into the new stadium and I'm sure they're looking forward to moving in."
