Australia head coach Andrew McDonald feels the absence of Mohammed Shami during the marquee Border Gavaskar Trophy next month is a huge loss for India but stressed that the hosts won't underestimate the quicks stepping in for the seasoned pacer.
Shami, who had played a significant role in India's successful 2018 tour of Australia, has not played since the ODI World Cup final last November due to an ankle injury.
He underwent surgery and was rehabilitated at the National Cricket Academy (NCA) but developed swelling in his knees which affected his rehabilitation.
"Mohammed Shami is a big loss," McDonald 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,” he added.
India have handed maiden call-ups to Delhi speedster Harshit Rana and Andhra seam bowling all-rounder Nitish Kumar Reddy while quicks Akash Deep and Prasidh Krishna have also been selected for the upcoming series.
Jasprit Bumrah will lead the fast-bowling department.
"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," McDonald continued.
Australian teenager Sam Konstas, who announced himself with twin Sheffield Shield centuries for New South Wales earlier this month, is in the reckoning to partner Usman Khawaja at the top in the five-match series.
"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," he said.
McDonald said that if the selectors believe the 19-year-old is the best choice, he will receive a Test debut, regardless of his lack of first-class experience.
"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 of filling that spot I don't think that the opponent should come into the equation,” McDonald maintained.
Australia will host India for the Border Gavaskar Trophy, starting November 22 in Perth.
