Victory eyes long-term signing

Postecoglou's first A-League win at the helm of Melbourne Victory - a 2-1 defeat of previously unbeaten Adelaide United on Friday night - came after a difficult fortnight in which his players have been put on notice the new coach will settle for nothing less than the best.

Veteran striker Danny Allsopp retired during the week - a move which has freed up squad space and cash under the salary cap to allow a quality signing.

But Postecoglou hinted that quick-fix types were not on his shopping list.

He says he needs a player capable of providing Victory quality and longevity, rather than just a stop-gap.

"Every decision that I'm going to make, I'm going to make this football club a better club in the long-term, and give us sustainable success," Postecoglou said.

"We're not going to go out and get someone for the sake of it because we've got a bit of room.

"If there's somebody out there who we think will fit into what we're doing ... it's a defined and rigid structure, they've got to fit into what we do.

"If they don't we won't bring them in."

Postecoglou will have to sign an Australian player, with all possible visa spots taken at Victory.

But Victory's allure and a good wad of cash is likely to link it with any Australians seeking repatriation from abroad - a ball-playing defender and attack-minded player the two most obvious gaps.

Postecoglou paid tribute to Allsopp, the 34-year-old whose hamstring gave way in the 5-0 loss the previous weekend to Brisbane, for making a selfless decision to quit and allow the club to move forward.

"I have great respect for Danny for making that decision because a lot of people in his position probably wouldn't have - they'd have played out the year," Postecoglou said.

"His attitude's been first-rate, but he was honest enough to say it was time for him, and it does give us some (squad) room."
