Viduka, who bagged a brace in Sunday's 2-2 draw with Derby, could dump the Socceroos as they embark on an exhausting schedule of 14 World Cup qualifiers in February.

He admitted: "The Asia Cup in the summer left me feeling jaded. It took it out of me mentally more than physically and that held me back at the start of the season. I'm starting to get back into it and these two goals will help.

"I haven't made a decision about Australia yet. I'm going to have a meeting with the manager soon and we'll discuss it.

"It's pretty hectic, there are midweek games where I'd have to fly to Australia or Iraq and that takes it out of you."
