Salford City Reds are prepared to splash out £650,000 to sign Kiwi superstar Sonny Bill Williams.

Reports from Australia claim a lucrative one-year offer from Salford is on the table for 28-year-old Williams who is out of contract with the Sydney Roosters at the end of the season.

Reds owner Marwan Koukash has been chasing Williams for the past six months but is refusing to reveal the exact details of his latest bid.

Koukash declined to comment but hinted at possible developments.

Salford’s interest in Williams was exclusively revealed by M.E.N. Sport in early July when Koukash lined up a meeting with the player’s representatives Salford face competition for Williams’ signature from rugby union with the Waikato Chiefs and Montpellier also interested.

Koukash has told head coach Brian Noble he will do everything in his power to try and land Williams but faces a battle.

Reds’ offer is understood to also allow Williams the opportunity to also pursue a career in boxing if he so wishes.

Williams was a target for Wigan in the past and Warriors’ boss Ian Lenagan also put plans in place for Williams to box.

A deal never materialised though with Williams who is never keen to commit to any club for longer than just one season.

Reds Kiwi director Andrew Chalmers has been in talks with Williams about a proposed move to Super League with Salford.

Chalmers met Koukash at Friday’s home game with Leeds for an update.

Koukash first considered a move for Williams mid-way through the season but plans were put on hold when Super League clubs voted against the idea of allowing one high profile player to be exempt from the salary cap.

That decision angered the Reds’ boss who believes such a scheme could have paved the way for the possible signing of either Williams or another hgh profile star in the NRL.

Williams has played rugby union in the past and Salford may not be able to compete with the money that could be offered to him by wealthy Super 12's club sides.

Reds coach Brian Noble is also a huge fan of Williams and has made no secret of his desire to see the strong running back rower play Super League.

Williams is expected to play in the forthcoming World Cup.

New Zealand want him but there is also the possibility of him representing Samoa who will be coached by former Salford boss Matt Parish.

Meanwhile, Hull KR and Castleford are leading the chase for Salford prop Lee Jewitt who may be on his way at the end of the season.

Noble has also sounded out Bradford’s Jarrod Sammut who played for him at the Crusaders and is also tracking former Parramatta and Cronulla play-maker Tim Smith who is currently at Wakefield.
