St Helens are the only Super League club not to have made a signing ahead of the 2020 season, but new head coach Kristian Woolf is confident the reigning champions can still improve as they aim to follow up a stunning campaign.
Under Justin Holbrook, Saints romped to the League Leaders' Shield last term for the second year running, before securing Grand Final glory at Old Trafford with a victory over Salford Red Devils.
Given that Saints lost only three league games in 2019, Woolf would appear to face a daunting challenge in succeeding Holbrook, who departed to join Gold Coast Titans in the NRL.
However, the new St Helens boss is optimistic there is even more to come from the squad he has taken over.
Asked about the club's decision not to bring in any new players even though several rivals have made eye-catching signings, Woolf told Omnisport: "We had the ability to make changes if we wanted to. I look through the roster and I think it's a very strong roster across the park and doesn't need change.
"They certainly showed that last year and again there's still improvement in the group. So if we can find improvement we're gonna be competitive.
"We're also blessed with the fact that coming through our academy we've got some very good juniors that, when we need to at different times through the year, they're gonna step up and they're gonna do a great job for us. They're Super League players in the making so certainly at this point I don't think there's any need for change."
Woolf added: "I've been really impressed since I've been here with the playing squad as a whole and what their capabilities are as players, but also just the fact that they're a very humble group.
"It's a new challenge [for me] and it's a different challenge. What we've been able to do is identify a couple of things that we think we can improve and there's obviously a lot of things at the club that have been done really well in the past that don't need improvement and don't need change.
"Getting that balance between finding improvements, but not changing things that aren't broke, that's my challenge and that's something the players have really bought into."
Saints kick off the season on Friday with a rematch of their Grand Final against Salford.
