Former Australia leg-spinner Shane Warne believes that drastic changes are needed in the Australian setup, suggesting that some members should be sacked in order to have a major clean out in the Baggie Greens’ setup.

While Steve Smith and David Warner have been relieved of their captain and vice-captain duties, the other member of the institution were untouched. Darren Lehmann, meanwhile, took it upon himself to resign from his post after Cricket Australia decided to not sack him.

Shane Warne, meanwhile, believes that there should be a massive clear-out in the system and be replaced by people that are zealous about the game.

"Australia need new people who are passionate about the game in charge, but understand the game,” Warne said to Supersport.

"Australia can be a force again, but need the right people involved. There is a huge opportunity now for players and people to be leaders. All positions are in jeopardy and need to be looked at, heads must roll."

He then continued to put on the heat on CA President James Sutherland and high-performance chief Pat Howard, asking for a review of their work before suggesting that Australia lack proper batting coaches and that all of the people involved with CA need to be held accountable for the dismal outing in South Africa.

"Every single position on the field, off the field, starting from James Sutherland at the top, Pat Howard who is in charge of cricket excellence, all these people," Warne was quoted as saying.

"The coaches. Batting coaches -- when are we going to produce a good batsman?
