If selected – and Bayliss appears keen to blood young players now the series is decided and a whitewash avoided – Crane would become England’s third debutant of the series after Craig Overton and Tom Curran.

“With the series lost it gives us the opportunity to look at some different people,” Bayliss said.

“There’s no time like the present to find out if Mason is ready. We think he’s a guy that has got the goods and the more he plays at this level the better he will get. You have got to start somewhere.”

Although his debut would come in a dead-rubber, with England having surrendered the Ashes in Perth, Crane hammered home his confident attitude by adding: “Even if it was a series decider and I was called upon, I’d be confident I could do a job.”

Former Australian leg-spinner Stuart MacGill acted as Crane’s mentor during his memorable winter in Sydney last year, and has also joined the England set-up this week as they prepare for the finale. Having been omitted from Hampshire’s first XI at the beginning of the last English season due to unfavourable conditions, and then taking just 16 Championship wickets at 44.68 in 2017, Crane has nevertheless earned the faith of Bayliss and MacGill.

Australia have also added left-arm spinner Ashton Agar to their squad for the final Test, but neither side has yet committed to a two-spinner approach despite the SCG’s reputation as a spin-friendly ground.
