"I think Rishabh has inspired a lot of wicket-keeper batters around the world to play that [aggressive] way. It is fascinating for such a young man to have such an impact that Rishabh has had, and others are responding and playing in that positive manner," Gilchrist, who is in India on a promotional visit, told PTI.

"They [India] are well stocked," Gilchrist said. "They have got a couple of [wicketkeeping] options there, obviously, when KL was out with his injury, Ishan Kishan took his opportunity and played really well, and now they find themselves in the team together so that's a wonderful case of taking an opportunity.

"Being positive, and then, forcing the selectors into keeping you in the team [is impressive]. It seems like KL is gonna be the one who is going to continue with the gloves but it does not seem to hinder Ishan Kishan's batting, he seems to be playing really well, carefree, attacking and dangerous."

Gilchrist picks his World Cup semi-finalists

"Australia will learn a lot from their efforts in South Africa when they come to India. They have got three games before the World Cup against India. So, they will have a bit more of a full-strength squad there, that might tell us a bit about where they are at.

"Adam Zampa, in South Africa, was at the receiving end a little bit but it's different conditions out here in India with different pitches and he is a world-class spin bowler, and he has shown that particularly across T20 cricket, and now he gets his chance in the 50-over World Cup. So it's a very knowledgeable group and they are going to have to use all that experience against batting line-ups across the globe and play without fear."
