Handscomb was retained in Australia's squad but is still facing the axe for the Boxing Day Test against India after a series of failures against India.

The 27-year-old scored 34 and 14 in Adelaide, before following it up with seven and 13 in Perth.

His second-innings dismissal in Perth - when he was trapped plumb lbw deep in his crease by Ishant Sharma - raised further worries about his unorthodox technique.

Test great Shane Warne labelled Handscomb a "lamb to the slaughter" after watching that dismissal.

And with Australia likely to need more bowling firepower on a notoriously flat MCG wicket, allrounder Mitch Marsh could replace Handscomb in the XI.

"The only thing I've spoke to him about so far is that I wondered if he was watching the ball," Langer told Cricket 360.

"Because there were times where he was probably playing back to balls he could've played forward to, and he was playing forward to ones he probably should've played back to.

"To me that's toughest thing about Test cricket, concentrating on the next ball.

"When there's all this noise and distractions, that's the courage and skill of Test cricket.

"For anyone to say that I think Handscomb has got to change his technique - well maybe where he can shuffle around where he stands he can change his intent.

"But that's his game. That's how he's probably going to be for the rest of his career now."

Langer is confident Aaron Finch will be passed fit to play despite the opener injuring his right index finger in Perth.

Finch was cleared of any break to his finger and was able to bat again, but he failed to take the field during India's second innings.
