Solomona has two years left to run on his Wakefield contract

The 28-year-old Test second row has two years left to run on his Wildcats contract but has requested a release.

The news follows the launch of a League probe into an alleged illegal approach for Solomona by the Bulls.

"We'll certainly express interest but a deal must be realistic and affordable," said Bulls chairman Peter Hood.

"We are always interested in quality players and he is certainly a considerable talent. That is beyond question."

Wakefield reported the Bulls to the League, claiming they tapped up Solomona while the club were still battling for their Super League lives.

We now have a key player who is unsettled because he has been offered a better financial deal elsewhere Wakefield chief executive Steve Ferres

Had the Wildcats been relegated, Solomona would have become a free agent but could now cost as much as �200,000.

Wakefield say they will reluctantly grant Solomona his release but only if they receive a satisfactory offer.

"The club is obviously disappointed and indeed devastated," said Wakefield chief executive Steve Ferres.

"He is one of the best forwards in the game and an integral member of the Wildcats squad.

"David made a verbal request to leave a couple of days after our last game of the season and was asked to reconsider his position. Unfortunately, he has now confirmed his demands to leave the club.

"Solomona and his agent have been told that his release will only be granted if the terms of his transfer are acceptable to the club and we are extremely annoyed and disappointed that we have been placed in this situation.

"We now have a key player who is unsettled because he has been offered a better financial deal elsewhere."

Solomona joined the Wildcats at the start of the 2004 season from Parramatta after a previous spell with Sydney Roosters.

He was named in the 2004 Super League Dream Team after helping the Wildcats reach the play-offs for the first time.

Solomona was recalled to New Zealand's side for last year's Tri-Nations and played in the 24-0 defeat of Australia in the final at Elland Road.
