Head, 24, has played 55 limited overs matches for Australia but appears set to become the first Redback to don the Baggy Green since teammate Chadd Sayers made his debut against South Africa in March.

Left-hand batsman Head impressed during Australia A’s tour of India and scored 90* in Australia’s drawn tour match against Pakistan A in preparation for the two-Test series.

Langer said Head and uncapped Victorian Aaron Finch were ready to represent their country in the Test arena.

"There was never any doubt over those two for me, I thought they were certainties to play," Langer said.

"Travis Head – his improvement over the last … six months is absolutely amazing. He's starting to look like an AFL footy player, he's really fit. The way he's adapted his game and improved his game, particularly against spin.

"He played brilliantly in the Australia A stuff, he's really impressive and he deserves to have a Baggy Green cap."

Head is expected to strengthen Australia’s middle order while Finch is likely to open the batting.

Marnus Labuschagne and Michael Neser are also in the mix to debut in what will be Langer’s first Test as Australian coach.

Queensland batsman Matt Renshaw is in doubt after suffering a nasty knock to his helmet while fielding on the second day of Australia’s tour match.
