England director of men's cricket Rob Key says he "wouldn't be surprised" if Ben Stokes came out of international retirement at some stage, adding "anything is possible". Former captain Stokes, 35, announced his decision to retire from international cricket during England's third Test defeat by New Zealand in June. Key said the door remains open for Stokes to return for next summer's home Ashes series against Australia - although he has received no indication that Stokes intends to reverse his decision. Former England captain Michael Vaughan believes the appointment of Fleming and Root's return as Test skipper might tempt Stokes to return to the England set-up. "Root's difficulty will be getting a structure in his team - getting a formula without an all-rounder like Ben Stokes," Vaughan told BBC Sport.
