Former England captain Michael Vaughan has admitted to pre-Ashes concern following the shock announcement that Australia have sacked Micky Arthur and appointed Darren Lehmann just 16 days ahead of the first Test.
Following overnight speculation that Arthur was to be relieved if his duties, Cricket Australia released a statement early on Monday confirming that the South African had been dismissed as head coach.
"This has been a difficult decision to make but one that we feel is necessary. We are looking to establish a high performing Australian cricket team that is consistent over a period of time," said Cricket Australia CEO James Sutherland.
"To achieve that, we need all the parts moving in the right direction. Recent on-field results have been too inconsistent.
“Discipline, consistency of behaviour and accountability for performance are all key ingredients that need to improve. And we see that the head coach is ultimately responsible for that."
Lehmann replaces Arthur, effective immediately, following success at domestic level with Queensland, where he has won the Sheffield Shield, one-day cup and Big Bash during the last two years.
The 43-year-old made 27 Test appearances for Australia, while he also featured in 117 one-day matches, and is an experienced operator in England, having played for a number of years at Yorkshire.
Lehmann is a former teammate of Vaughan from his time at Headingley, and the latter believes his ex-colleague is the ideal person to revive Australia's fortunes ahead of the Ashes, with the first Test set to begin on July 10 at Trent Bridge.
Vaughan tweeted: "The Aussies might not have the players of old but @darren_lehmann will install real fight into the side... #Worried."
