Milligan, 27, has been linked with the newly-promoted English Premier League club although au.fourfourtwo.com spoke with his agent late this week who denied a bid had been tabled.

However, speculation is rife about Milligan's future amid reports of further interest from QPR and clubs in the Middle East.

When asked if he would prefer to see Milligan turning out every week for Victory or competing for a place in a Premier League side, Osieck acknowledged the player has a difficult decision to make.

"Having a spot more or less secured in his home team (Victory), but even there he is not guaranteed (to play) if he doesn't perform," he said.

"And having the opportunity to play in one of the top leagues in the world (is tempting). He is that kind of character that he would fight through (to win a place) if given the opportunity.

"It's down to him, it's his discretion as to what is best for him. What's important to me is he plays regularly."

Osieck was also adamant he would not advise Milligan in favour of either course of action, preferring to remain neutral.

"I would never do anything like that," he said when asked what he would say if Milligan came to him for advice.

"I can't offend our domestic league and I'm not an agent of a foreign team."

Another player whose future is uncertain is Matt McKay, who was released by Changchun Yatai on Friday and will be seeking a new club for the coming season.

Osieck is confident the experienced utility will be snapped up quickly, and expressed his surprise at the Chinese Super League outfit letting the former Brisbane Roar star go.

"He is a player that everybody would like to have on (their) team, obviously except for his Chinese (side)," he said.

"I'm really not worried about that. He's still an important member of our squad. It's not to his disadvantage."
