Key Socceroo Mark Bresciano may risk his World Cup ambitions by taking on FIFA over a four-month ban for an alleged illegal transfer.
The governing body hit Bresciano with the lengthy suspension – and a $1.9m fine – after ruling his move from Qatari club Al Gharafa to UAE outfit Al Nasr was not legal.
If he accepts the decision Bresciano could be back playing before the World Cup.
But any appeal could drag the process out and potentially rub him out of next year's World Cup in Brazil.
Despite that danger, the veteran Australian midfielder indicated he was willing to fight the case.
"It's not an illegal transfer, there was nothing done illegally," Bresciano said after the Socceroos' 1-0 win over Costa Rica on Tuesday night.
"I was surprised when it came out. I think there is a good chance we will fight it.
"I'm getting the best legal advice so I think in the next couple of days we'll make a decision."
Bresciano managed to put the drama behind him to play a pivotal role in Australia's win in the friendly, later revealing he had leaned heavily on those around him.
"It was a bit tough for me but my teammates, the environment around me, FFA, my friends and family ... I got all the support I need," he said.
"It's a tough situation but I'm sure I'll get through it."
FIFA has not stipulated when the ban is set to start, with Bresciano to wait until he returns to the UAE before deciding his next move.
"I have to wait until I get back to my club. I have been told not to say much because it's a legal matter," he said.
"I'm just weighing up my options and we have to see what we can do.
"I'm getting the best legal advice so in the next couple of days we'll make a decision."
