Gavaskar was of the opinion that with Wriddhiman Saha, Ravichandra Saha and Ravindra Jadeja in good nick, India can afford to bring in a fifth bowler in the playing eleven to share the burden of its four-men bowling attack.
"India's batting has benefited by the fact that you have somebody like (Ravichandran) Ashwin, somebody like a Wriddhiman Saha at No 6, 7 and 8. And if Jadeja can come score runs as he has done in this series then I think it really makes sense to go back to five bowlers and six batsmen theory," Gavaskar told NDTV.
The former India captain also differed with Australia captain Steve Smith and said it is not the visitors but India who has the momentum on its side going into the fourth and final Test in Dharamsala starting Saturday.
"I think the momentum is still with India because they are ones who came back, having batted second and chasing 450 plus score. They might not have bowled Australia out but I think the momentum definitely is still with India," Gavaskar said.

Gavaskar also praised Peter Handscomb and Shaun Marsh for their their gritty batting effort to bail Australia out in the game.
The duo stitched match-saving 124 runs for the fifth wicket to deny India a win.
"I think the way these two (Handscomb and marsh) batted, they denied India a win. It was good old fashioned Test match batting. It didn't mean that they were playing for a draw from the first ball of the game. It's fine when you find that you are not in a position to win then it's better to save the game and live to fight for another day. And that's exactly what the Australians have done because if Australia would have lost today, it would have been an uphill climb. Now they have an opportunity to win the series," he said.
