Warburton will lead Wales in the game against the famous invitational side at the Millennium Stadium and is looking forward to facing his fellow Cardiff Blues openside.
“Playing against Martyn will be interesting and certainly different to training against him,” he said.
“He’s someone I’ve looked up to ever since being a teenager playing rugby and it still seems strange being in the same squad let alone playing against him.
“He’s been a massive part of my development and I probably have more respect for Martyn than any other player.
“He’s been really supportive and may not know it but I study parts of his game very closely. I try to take the good aspects from his game and implement them into my own.
“That’s easier said than done because he’s such a quality player.”
Warburton is anticipates a real battle against the 98-cap international and is bracing himself to come up against almost every trick in the book.
“Martyn knows a few of my weaknesses and will try to expose me. I guess both of us know where to have a crack at each other. But we’re good friends and there certainly won’t be any cheap shots.
“It’s going to be a great spectacle and will suit Martyn down to the ground. We’ll just try to enjoy the occasion.”
But Williams insists it will be more of a case of the apprentice teaching the master what he has learnt when the two sevens clash.
Williams added: “He’s probably taught me more than the other way around. He keeps his feet on the ground and will become a huge star for Wales and a British Lion several times.
“He’s a great athlete, he’s physical, very strong, defensively he’s an animal and he carries very well. It’s the top two inches with Sam. He’s the first to analyse his game and always wants to improve. He’s going to get better and better.
