The Bulldogs will be given one final opportunity to retain strike centre Nigel Vagana, but the National Rugby League club looks to be fighting a losing battle.

Cronulla appears certain to make the Kiwi Test player its second major signing - following the earlier recruitment of Sydney Roosters prop Andrew Lomu.

Vagana held talks with the Sharks and Cronulla officials are optimistic they have done enough to entice the league's try-happy centre to the Shire.

"Nothing has been finalised at this point in time," Cronulla general manager Steve Rogers said.

"We're optimistic.

"I'm hoping it could be as early as tomorrow. There's some issues that we need to address.

"Once we get them out the way hopefully we can finalise the entire deal."

Vagana, who has also had approaches from England, wants to remain in the NRL and is not short of options.

Apart from the Sharks and Bulldogs, the Wests Tigers and Warriors have been linked with the New Zealander.

However, the race for his signature appears to be down to two clubs - the Sharks and Bulldogs.
