Ben Stokes and Brendon McCullum have been in charge of the England Test team since 2022
Coach Brendon McCullum believes his England team are ready for an Ashes series that could "define" them.
McCullum and captain Ben Stokes have revitalised the England Test team since taking charge in 2022.
The New Zealander said they have been "building to this moment", with the first Test against Australia in Perth beginning on Friday (02:20 GMT).
In his only interview since arriving in Australia, McCullum told BBC Sport: "There's nothing bigger than what we're about to come into."
