ICC had previously trialed four-day Tests some time back.
Former England captain Michael Vaughan has advocated for Test cricket to be reduced to four days, noting the faster pace of modern games and the need to reach a larger audience.
Vaughan believes the change would be consistent with the format's developing nature, in which results are frequently obtained in three or four days. Vaughan advocated a fixed Test match schedule that would run from Thursday to Sunday.
"It'd start on a Thursday and finish on a Sunday. It would be easy for everyone to understand that Test cricket starts every Thursday and finishes on a Sunday... if it makes it to Sunday,” Vaughan said on SEN Afternoons.
Vaughan highlighted the transformation in playing styles over the years, which he argues has rendered the fifth day unnecessary.
"Let's be honest, the way that the players go out and play their business now, they don't play like I used to play or some of the teams back in the 80s and 90s played. They’re playing a brand of cricket which is pretty much to try and win as quick as they possibly can and put the opposition under pressure,” he added.
The present Border-Gavaskar Trophy between Australia and India has already concluded quickly, with the first Test ending on Day 4 and the second in three days. Vaughan proposed that the quicker results fit well into a four-day framework, making the game more viewer-friendly and easier to arrange.
"We've got players that are incredibly entertaining now. Four-day cricket would be easier to schedule. The administrators around the world need to seriously consider if it’s time to go from five days to four,” Vaughan signed off.
