David Warner has admitted he is still unsure if he is ready to take part at the SCG for the third Test after admitting he must still prove himself as the star batsman attempts to prove his fitness.
Warner has been on the sidelines since suffering a groin injury during an ODI on November 29.
'SORRY HOW?': Cricket world in awe of 'outrageous' superman catch
Australia, reeling from a shock loss to India in the Boxing Day Test, are desperate for the 84-Test veteran to return at the SCG and bolster their misfiring batting order.
Warner says he will have a better idea of whether he will play the third Test, which starts on Thursday, after training in Melbourne on Saturday and Sunday.
"It'll probably give me a better indication," the 34-year-old told reporters on Saturday morning.
"Am I going to be 100 per cent? Highly doubtful.
"But I'll be doing everything I can to let the selectors give me that green light."
Warner waiting on fielding fitness
Warner suggested his capacity in the field will likely determine whether he returns to Australia's XI in Sydney.
"I know I can manage the running between the wickets, the shot making I have," he said.
"Whether it's standing in the slips cordon, taking catches to my right and left ... I need to be agile enough to make sure I'm taking those chances.
"Not be a hindrance there."
Warner revealed the injury may restrict his ability to play certain strokes but argued adrenaline would take over during a match and his trademark speed between the wickets was more important than his full array of shots.
The opener, if selected, declared he is ready to partner Matthew Wade, Will Pucovski or Marcus Harris at the top of the order.
