Manly have started negotiations with Brett Stewart to ensure the premiership-winning fullback finishes his career a one-club man.

Stewart is off contract at the end of 2016 but has indicated he is hopeful of continuing in the top grade into his mid-thirties. Having copped a savage backlash over the decision not to table Stewart's brother, Glenn, a contract extension last year, Sea Eagles powerbrokers are keen to ensure there isn't a repeat in negotiations with the man dubbed "The Prince of Brookvale".

Stewart has overcome a series of horrific and potentially career-threatening injuries in recent years to emerge as the most prolific try-scorer at Brookvale Oval. In a recent interview, Stewart said he was capable of at least "another three or four years" in the NRL and would like to play on until the end of 2019.

"If I can get another three or four years, I can't see a problem with that," Stewart said last month. "My hamstrings have been the biggest hurdle the last few years, but I'm over that now and I'm fit."
