Sea Eagles chief executive Lyall Gorman said the club would not be responding to a report that coach Trent Barrett has quit the club and will leave at the end of the season.
When contacted by NRL.com on Tuesday night, the Manly CEO said he would refrain from making any public comment apart from an email to club members released earlier in the day.
Gorman would not elaborate on Barrett's status in the wake of the report published by News Corp.
"You will continue to see speculation over the coming days in relation to the future coaching structure at our club and indeed across the NRL," Gorman said in the email released earlier in the day.
"As outlined in my letter to you recently, the club's singular focus at the moment is on its last three games and ensuring that we finish as high up the NRL ladder as possible.
"To that end the club will not be embroiling itself in the constant speculation around coaching movements either within our club or indeed, across the NRL.
Manly players talk about Barrett's future
"While it is fair to say our club, coaching staff and our players have endured a challenging season be assured that they are working incredibly hard to win our last three games, starting with the Titans this Friday evening at Lottoland.
"Should our club wish to make any announcement in relation to its future staffing structure, now or into the future, be assured that as our valued members and supporters, you will be the first to know.
"In the interim, it would be a great way to finish our last home game of the year to have as many of you as possible join us on Friday night as we seek to provide you with the end of season finish that you, and everyone associated with our club deserves."
Earlier on Tuesday, Sea Eagles, NSW and Australian forward Jake Trbojevic said he expected Barrett to be at the club for the long haul.
"I love him as a head coach, he's a great leader, a great man, and he's a great coach," he said.
"I love playing under him, I hope he's my coach for the whole of my career.
"I don't think there is too much to worry about, he came out and said it was all speculation. Nothing too much to worry about."
