Hasler's future is under the microscope following a horrid season for the men from the Northern Beaches.
Manly found themselves out of finals contention during the final weeks of the season, going on a staggering seven-match losing streak to close out a season where the club never hit their potential.
The dramatic slide down the table, not aided by injuries throughout the course of the season, was impacted heavily by injuries, but internal reviews have been underway at the club since the season concluded.
It was eventually stated that Hasler would keep his job, but under new conditions.
He is out of contract at the end of next year, and while he reportedly wants to coach until the end of the 2024 season before being replaced and moving into another role, the Sea Eagles have reportedly identified their target replacement.
The publication reports that Ryles, who only arrived at the Roosters this year, is in no rush to exit Bondi, but could be open to taking a head coaching job down the track.
It's understood the fact he is on contact at the Roosters until the end of 2024 may provide Hasler some extra breathing space in the role and the ability to potentially go out somewhat on his own terms at the end of that season.
