REDS chairman Greg Griffin has rejected claims Harry Kewell is still on the hunt for an A-League club.

Socceroos manager Bernie Mandic recently reignited the debate.

Mandic told Melbourne radio Kewell had not signed for Melbourne Victory, but Griffin believes the superstar wouldn't choose any other club.

Speculation is pointing towards Kewell being officially unveiled when the Victory hosts Scotland's Glasgow Celtic at AAMI Park on July 13.

It's understood Kewell has put pen to paper in a deal which would command a minimum wage and receive 80 per cent of any additional revenue Victory receives from bumper crowds at Etihad Stadium and AAMI Park.

Griffin said Adelaide was never in the running for Kewell because Hindmarsh's 16,500 capacity wouldn't be lucrative enough for the Socceroo to command a decent salary as part of the revenue agreement.

"We have a strong belief that Harry has already agreed to play for Melbourne Victory," Griffin said.

While United won't get Kewell, Brisbane Roar coach Ange Postecoglou has been given the green light by Football Federation Australia - the club's interim owners - to chase him.

Mandic mentioned A-League champions Brisbane as a potential home for 32-year-old former Leeds, Liverpool and Galatasaray star.

"They've got a sensational team ... a great coach who's earned his stripes in Europe, they've got a stadium waiting to be filled," Mandic said.

"He's a once-in-a-generation player," Postecoglou said.

"If it could be done, I'd love to have him in Brisbane."

Mandic last night told The Advertiser he would not publicly discuss his client's dealings.
