Manly has given hooker Apisai Koroisau permission to speak to other clubs despite having over two years left on his current contract.
Injuries have limited Koroisau to 27 matches since the start of last season, which has allowed 21-year-old Manase Fainu to emerge as the Sea Eagles' starting dummy-half.
According to The Sydney Morning Herald, three clubs have expressed interest in signing Koroisau for the 2020 season.
The Warriors are expected to part ways with Issac Luke at the end of the campaign and have already expressed interest in Koroisau, while Canterbury is another club to have shown interest although they are also in negotiations with Newcastle's Danny Levy.
Wests Tigers are the third club to show interest in the Fijian international as they expect Robbie Farah to hang up the boots at the end of the season. Tigers coach Michael Maguire won a premiership with Koroisau at South Sydney 2014 and would once again love to link up with the No. 9.
Manly have told Koroisau they will honour his contract if he is unable to find a new team, but their preference is to let him go as they need salary cap space to retain Tom and Jake Trbojevic.
