Wales coach Warren Gatland claims he will not stand in the way if England attempt to poach Shaun Edwards.
Eddie Jones is looking for a new defence coach after his side-kick Paul Gustard joined Harlequins just a year outside the World Cup.

World Cup winner Matt Dawson has claimed he is the perfect candidate for the Red Rose job - although official contact is yet to be made.
Gatland, however, has already held conversations with Edwards about his future and is prepared for all scenarios.

Reps: Ryan Elias, Wyn Jones, Rhodri Jones, Adam Beard, Aaron Wainwright, Aled Davies, Rhys Patchell/Gareth Davies, Hadleigh Parkes.

Gatland, however, is keen for Edwards to remain in Wales until the 2019 World Cup.
The pair have worked together for more than a decade - with Edwards signing up as a coaching
