The 30-year-old Alaves striker limped out of a training session on Monday with a foot injury and is poised to join Harry Kewell and Tim Cahill among the absentees for Thursday's 95,000 sell-out match against Greece at the Melbourne Cricket Ground.

"I'm quite positive I won't be able to play on Thursday," the former Coventry and Portsmouth striker told Australian Associated Press.

Aloisi struck the decisive penalty in November as Australia pipped Uruguay for a place in the finals in a dramatic shootout after their two-leg qualifying matches finished at 1-1.

Aloisi initially feared he had aggravated a foot injury sustained while playing for Alaves in the penultimate round of matches in the Primera Liga.

But after treatment with Australia team physiotherapist Les Gelis, Aloiso was confident he would be fit for the warm-up matches in Europe next month.

"It should be alright for the Holland trip, which is important because I don't want to get any further injury before I go away," Aloisi said.

The 23-man squad, minus Kewell who is undergoing treatment for a groin strain in England, will fly to Europe on Friday for tune-up matches against the Netherlands in Rotterdam (June 4) and Liechtenstein in Ulm, Germany (June 7).

Everton's Cahill has already been ruled out of Thursday's farewell match against the Greeks but trained with his team mates on Monday and reported promising progress with his knee injury.

"I've been working really hard on it and I'm more than hopeful it will be okay by the time we get to (the Netherlands) for the camp," Cahill said.

Australia have been drawn in Group F at the World Cup finals alongside champions Brazil, Croatia and Japan.
