"I think we're picking the best team for here and now, and if that does encompass a younger player, then we'll head down that direction," McDonald told ABC's Offsiders. "And clearly Sam Konstas, on the back of his first Shield match, and the way he went about his work in the second innings at the MCG against Scott Boland, has definitely made some noise.

"I've heard people commentating 'do you protect the player?' If they're ready, they're ready in our mind, and if Sam's capable and we feel as though is capable to fill that spot I don't think that the opponent should come into the equation."

"I think it's purely is this player good enough to play Test cricket?," McDonald said. "You've got to start against someone, and you shouldn't be holding back and protecting someone from a potential opponent, and India is a strong opponent but also the advantage of a player playing in Australia for their first Test summer is that the conditions are familiar. What better place to start than in your own back yard."

However, despite the decision to move Steven Smith back to No. 4, McDonald continued to believe that a middle-order batter could be converted to a Test opener if that was felt the best solution. McDonald has previously been strong on picking the best six batters available.

McDonald cited the examples of Watson and Simon Katich who moved from middle-order roles to the top with success while also drew on India's last visit when Matthew Wade took the role amid injury issues for first-choice options.

"The way our batters speak about his [Shami's] relentless nature, his line and lengths, the way he goes about his business, a real good complimenting skill set to Bumrah so think that one-two combo they'll lack a little bit, and they'll miss that."

"I think he's a legitimate chance to put his hand up for selection at some point in time, whether that be in the middle orderor whether that his technique can push for an opening slot," McDonald said. "I think he's technically capable and definitely got the mindset to be able to achieve good things at the top of the order, but whether that's the time and place for him right now, that's to be decided.''

"Mohammed Shami is a big loss," he said. "The way our batters speak about his relentless nature, his line and lengths, the way he goes about his business, a real good complimenting skill set to Bumrah so think that one-two combo they'll lack a little bit, and they'll miss that. But needless to say we saw what happened last time, they had reserves that came in and did the job as well so they cannot be underestimated at all."
