Former India skipper Dilip Vengsarkar and ex-Test umpire Piloo Reporter have welcomed the proposal to make four-day Tests mandatory instead of the current five-day format. However, former India pacer Raju Kulkarni warned that cricket will be played negatively in this 360-over game."

It was reported by ESPNCricinfo on Monday that the International Cricket Council (ICC) could make four-day Tests mandatory from 2023 as part of the World Test Championship, primarily to free up a crowded calendar. "Four-day Tests will become more competitive and entertaining. Captains will also change their strategy and may come up with innovative plans. It will bring in more excitement to the game and challenges for the players," Vengsarkar, a veteran of 116 Tests, told mid-day on Monday. "Earlier, there were three-day Tests matches. Then, it became four days and then five days. In the last five years, most Tests ended in four days, so it's a good move to have four-day Tests," added the former chief selector.
