Cricket Australia CEO James Sutherland and Justin Langer speak to the media during a press conference on May 3, 2018 in Melbourne, Australia. Langer has been appointed the Team Head Coach of the Australian men's cricket tea, replacing Darren Lehmann who resigned in the wake of the ball tampering scandal.

Australian coach Justin Langer's future is seeming more and more uncertain by the day, with another name thrown into the pool of candidates to replace him.

While Langer has led Australia to a T20 World Cup victory and Ashes series demolition of England, Cricket Australia senior officials have refused to back him for a new contract.

At this stage, his deal is due to expire as head coach of the Australian men's team in mid-2022, likely after the tour of Pakistan and before an upcoming proposed series away in Sri Lanka during the winter.

While it has been widely reported current assistant coach and former Test all-rounder Andrew McDonald is the favourite to replace him, The Guardian reports former England mentor Trevor Bayliss could be the man to take over.

The Goulburn-born 59-year-old has coached England and Sri Lanka at international level, leading England to the 2019 World Cup.

The report suggests those in the camp are now viewing Bayliss as the preferred candidate, despite the fact McDonald has coached Australian limited overs teams when they have played at the same time as the Test team, and is likely to lead a tour of New Zealand at the same time as a Test tour to Pakistan in February.

It's understood Bayliss is incredibly popular in the dressing room given he has coached many of the players at New South Wales level, and Bayliss has previously stated the Australian job is the only one he would contemplate in the future.

It's understood a consultation process over the head coach role involving players and staff will commence after the Ashes.
