Dolphins CEO Terry Reader, speaking before the sold-out battle with Brisbane on Saturday night, said the club was more than comfortable the 26-year-old England international would remain at the club beyond 2027.
In Reader's estimation the Roosters talk is exactly that - talk.
"They are rumours for a reason," Reader said.
"People forget Herbie was off contract last year and he was going to the Roosters but he re-signed with us.
"The reason the vacuum gets put in there is because our club operates outside the public domain when we're doing player negotiations and so does his management group.
"He's in a good environment, he's playing wonderful football and he's in a team that will be challenging (for a title).
"We've got every faith that Herbie will want to continue to be a Dolphin."
The connection to the Roosters has bemused Farnworth, who said recently he's had no contact with them.
"(The Roosters link) is just media talk. We haven't spoken to anyone and I certainly haven't heard anything," Farnworth said.
"I have not had any thoughts on leaving. I'm happy. When (contract talks) do roll around I will be speaking to the Dolphins first."
The England international is in a side destined for finals football and plays in a backline that includes star Queensland outside backs Selwyn Cobbo and Hamiso Tabuai-Fidow, both of whom are in negotiations to extend long-term at the club.
The Dolphins, who have up to 15 players off contract at the end of 2027, can't keep all their stars and the exits of Kodi Nikorima, Jamayne Isaako and Jake Averillo next year is all part of the salary cap matrix they are managing.
Affording Farnworth won't be an issue for the Dolphins.
"We've got a lot of players off-contract and Herbie is obviously one of the key ones," Reader said
"The November 1 deadline is a big thing for the media, and it also becomes a big thing for clubs because they can go to the open market.
"But a lot of our players went past that marker last year and we still re-signed them and nothing's changed."
Farnworth's centre partner Jack Bostock is another big name off contract at the end of next year.
"In Jack's case, he's an Origin player at our club. It's a wonderful environment that he enjoys and he's another one we'd be hopeful to keep," said Reader.
If money is the sole driver for players, as it may be with the tax-free dollars on offer at PNG in 2028, then Reader said "other clubs can't compete".
