Everton midfielder Tim Cahill admits he will be careful not to get injured for Australia against Paraguay today.
He says he wanted to once again demonstrate his commitment to playing for his country by linking up with the squad, but he is conscious of the fact his club will need his services when they face arch-rivals Liverpool on September 17.
"It's hard and it's up to the manager (whether I play)," said Cahill. "Obviously we have good personnel who can hopefully do a great job against Paraguay, but if everything goes well this week then I have every possible chance.
"There's so many players here who want to start and everyone's fighting for a spot, but I've got a massive derby to go back to as well."
