England rugby centre Jonathan Joseph says speculation the Wallabies may unleash Israel Folau as a centre for Saturday’s opening Test isn’t bothering the tourists.

Folau’s form at outside centre for the Waratahs in Super Rugby has sparked debate that Wallabies coach Michael Cheika may play him there at Suncorp Stadium than his usual fullback position.

Joseph says he’s been impressed by Folau’s form in the No.13 jersey but he and his teammates are prepared for either eventuality.
