DARIO Vidosic's agent says coach John Kosmina's public scolding has further disillusioned the Socceroo.

Following the 2-1 loss to Wellington Phoenix at Hindmarsh Stadium on Friday, Kosmina took aim at the playmaker saying "he chose the wrong option twice" when asked why Vidosic was replaced by Jacob Melling, 16.

Kosmina was referring to Vidosic's set-pieces.

"We're working hard to get the best out of Dario and have him settled and happy in his environment but comments like this don't help," said Vidosic's FIFA agent John Grimaud yesterday.

Brisbane Roar has until midnight to sign an unhappy Vidosic.

Despite his three-year deal, it's understood his last Reds game was to have been against Central Coast Mariners (2-3) on January 21 before negotiations were scuttled by Adelaide officials after the Roar had submitted a request to speak to him.

It appears Vidosic's chance of an early release depends on whether any club is willing to pay a transfer fee - unlikely given Europe has closed its doors until July while Asia and the US are still trading.

But Vidosic's last realistic hope of a move north is today, before the Asian Football Confederation closes its registrations window.

Adelaide, Roar and Mariners must submit their final squads of 30-players to the AFC while the A-League's transfer window is trading until St Valentine's Day. But Brisbane football manager Paul Trimboli yesterday confirmed Vidosic won't be on the club's Asian Champions League roster.

And Kosmina will break one foreign Reds heart when submitting the squad to the AFC as Adelaide can only field three imports registered outside the confederation's boundary.
