Langer will cover for coach Darren Lehmann who will be in India preparing for a four-Test series in February.

Langer beat out an array of potential suitors including Shane Warne and Mike Hussey who had both declared their lust for the role.

Langer said he was driven by the fact the Aussies had not yet captured the T20 world crown.

"Twenty20 international cricket is the one format in which Australia is yet to win a global tournament," Langer said.

"So every chance we get to play it and develop our skills is very significant.

"That means these three matches will be hugely important."
