The cricketing world has been discussing the proposal put forward by the ICC to have mandatory four-day Tests from 2023.
As of now, most of the cricketing experts have voted against it.
Former Indian Test opener Virender Sehwag, too, is against tinkering with the format and has compared the same with a diaper.
Here is more on what Sehwag said.
Diaper, five-day Tests should be changed when it's finished: Sehwag
Speaking on the issue while delivering the MAK Pataudi Lecture, Sehwag said that although he has always supported changes in the white-ball format, five-day Test is a different ball game.
"Innovations like names in jerseys and pink ball Tests are fine. But, diaper and five-day Tests should only be changed when it's finished, when it can't be used anymore," he said.
Test cricket is a 143-year old fit person: Sehwag
"Five-day Test is not finished. Test cricket is a 143-year old fit person. It has a soul. 'Char din ki sirf chandni hi hoti hai....Test cricket nahin' (four days of moon is fine, not Test cricket)," Sehwag added.
Here's how others have reacted to four-day Test proposal
Recently, Indian skipper Virat Kohli lent his support to the longest format of the game and doesn't want it to be altered.
The likes of Vernon Philander and Glenn McGrath had strongly voiced their opinion against four-day Tests as well.
Ganguly said it is too early to speak about the same.
However, board members from England and Australia are open to the idea.
