Jake and Tom Trbojevic's manager Paul Sutton has declared he is "unaware" of Canterbury's alleged big-money offer, according to The Sydney Morning Herald.
Fox Sports reported that the Bulldogs made a $10 million package bid for the brothers, $1.4m for Tom and $1.1m for Jake over four years – as well as a $4 milliion contract for rising Bronco David Fifita
Sutton revealed that brothers were yet to receive a new deal from Manly, despite being free to sign elsewhere from November 1.
The duo have repeatedly professed their love for Manly and coach Des Hasler but have also said they would consider signing big deals elsewhere.
Canterbury boss Andrew Hill told The Sydney Morning Herald: "There seems to be endless speculation about who we are in the market for, and we won't add to the running commentary.
"We're the same as every other club and will monitor player availability at the appropriate time.''
Daly Cherry-Evans said of the brothers: "They've become such a big part of the club, not just on a football level but at a club level because of how likeable they are.
"It would be a monumental loss if we let Tom and Jake go.
"To hear that [Canterbury news], I would never begrudge them doing what's best for them, but I really, really hope it's Manly who keep them.''
