Stephen Ferris claims that the big coaching changes with Six Nations rivals Wales and England heading into a Rugby World Cup year won't knock Andy Farrell's Ireland off-course in 2023.
Instead, Ferris warns, the biggest obstruction to Ireland's Six Nations success - and making it past a World Cup quarter-final for the first time - is Ireland themselves.
Warren Gatland made a high-profile return to Wales' hot-seat a fortnight ago as Wayne Pivac was let go, while Steve Borthwick left his job with Leicester Tigers to replace Eddie Jones as England head coach yesterday.
