Former Odsal coach Matthew Elliott is urging Twickenham target Henry Paul to re-sign with the Bulls.
The 27-year-old New Zealand international, who is out of contract at the end of the season, is thought to have been made an offer in excess of £1million to follow Jason Robinson into rugby union.
He is currently in talks with the Bulls about a new deal and has been considering a career in the Australian National Rugby League.
However, Elliott, now assistant coach to Mal Meninga at Canberra Raiders, told www.Rugby.com that he had advised the goalkicking stand-off to re-sign with the Super League leaders.
According to Elliott, no Australian club would be able to match the four-year offer from the Bulls, which would also allow him to spend two off-seasons in rugby union.
"He has a deal equal to about 600,000 Australian dollars (around £250,000) a year offered for four years," Elliott said.
"You'd get Ryan Girdler and two other players for that. I have a very good relationship with Henry. I told him he should get down there and sign that deal today.
"We're not in a position to compete with that. He really, really wanted to play in the NRL and he felt he needed the challenge.
"But at the end of the day there's no decision for him to make. There's no way that I could see any NRL club being able to compete with that."
Bulls chief executive Abi Ekoku said he expected the issue to be resolved within a fortnight, but denied that Paul was being offered the chance to play rugby union as part of the new contract offer.
"Talks are ongoing and we remain very confident that Henry will re-sign with us," said Ekoku. "I expect that in 10 days to two weeks it will all be resolved, but there is no pressure on Henry at all.
"It's a pivotal stage of his career and it's important that he makes the right decision. He's in a privileged position and he needs to take his time and consider everything."
