Former England captain Michael Vaughan said that Cricket Australia should have done more in their initial investigation of the 2018 ball tampering scandal.
Australia's bowlers recently said in a joint statement that they were unaware of changes being brought to the ball during the infamous third Test against South Africa, after Cameron Bancroft indicated last week that they may have been aware of it as well.
"Not many former professionals I have spoken to believe something like that would be confined to just three people. There might be some in a dressing room who may not like it and disagree with a course of action, but say nothing because they do not want to go against the captain. I can see how that happens," Vaughan wrote in the Sydney Morning Herald.
