“It is tough when you are up against it and you need to shake that negative energy I guess and move on,” the Bristol Bears prop added.
“A week like South Africa at Twickenham is probably the best week to do so.
“Everyone thinks they are amazing, myself included, I think they are a great team. I’d love to get after the best.”
