Justin Langer feels Steve Smith might not want the Test captaincy back as his ban on leading Australia ends in March next year.
Smith was leading his side as he was suspended for 12 months over a ball-tampering scandal which emerged in Cape Town last year.
There have been talks around giving back the captaincy role to Smith following his incredible run of form in the Ashes which helped Australia retain the urn.
But Langer said the decision wasn’t easy for the star batter following the mental and physical toll of leading the side.
"I've built a good relationship with Steve over the last 18 months, and it (the captaincy) is going to come down to honest conversations," the coach told the Australian Broadcasting Corporation on Saturday.
"You can see how exhausted he was from the effort he put into his batting (during the Ashes), and whether he wants the burden of captaincy as well is something we'll have to work out over time.
"I'll be one of the selectors, and I think we'll just work out what's best."
Paine is most likely to lead the side in the home Tests against Pakistan and New Zealand despite a lot of criticism on his batting performances as a skipper.
But Langer showed full confidence in the 35-year-old, saying he was "doing a brilliant job at the moment".
"He's been outstanding in his time as captain. However long he wants to keep playing for is another thing," he further added.
Langer showed a lot of trust in David Warner as well who recently scored his 29th first class hundred against Queensland in a Sheffield Shield clash.
Stuart Broad had complete wood over David Warner in the recent Ashes, removing him seven times in five Tests.
"He had a poor series against England, no doubt. That's just a fact, and he knows that," Langer said.
"But he also hasn't lost his talent, because he was the highest run scorer in the World Cup two weeks before the Ashes started, and he was the highest run scorer in the IPL (Indian Premier League) before that. So he can bat.
"The other thing about David Warner, my experience tells me that you never write off champion players. And he's a champion player."
