Trevor Bayliss will step down as England coach when his contract expires at the end of the 2019 Ashes.
The 55-year-old, who was appointed in 2015, has just seen his side beaten 4-0 in Australia, but told England director of cricket Andrew Strauss of his plans a year ago.
“I’m contracted to September 2019 and that will see me out,” the Australian told BBC Sport.
“I’ve always felt that it’s time for a change around that four-year mark.”
He added: “A new voice and a different approach reinvigorates things.”
