To see the FFA's goodwill trip to a South African school...

Jones' four-year-old son Luca has been diagnosed with leukaemia and Jones is by his side in a southern French hospital. 

"For the moment it's wait and see with Luca, but the treatment will last for five weeks and I want to be here as much as I can," he told News Ltd.

"I've thought long and hard about whether I should come back but I think I will stay."

Jones, who has been touched by the support from the Socceroos and those outside the Australian camp, is putting all his energies into helping Luca with the treatments that lie ahead.

"The World Cup is irrelevant for me now," Jones said.

"When I walked into the room and he smiled when he saw me, that was worth more than anything and more than a World Cup could ever give me.

"I feel a bit helpless not being able to communicate with the (French) doctors, but it's worth it by him just knowing that he's got me here."

The Socceroos have special dispensation to replace Jones from FIFA with Adelaide United's Eugene Galekovic expected to be added to the squad.
