"He's a really good player," said England coach Steve McNamara. "You have to work together. If you try to stop Roger on your own he will embarrass you. If you work together collectively you have a far better chance of preventing him doing the special things that he can do."
In his assistant's role at the Roosters, McNamara has had a close view on Tuivasa-Sheck's ability; perhaps both a blessing (insider knowledge) and a curse (sleepless nights over how to stop him).
Kiwis prop Sam Moa felt McNamara's time at Bondi would be an advantage.
"There is a large Roosters contingent on our side...no doubt Steve will be dishing out the dirt on us," said Moa. "He will be trying to give his team our weaknesses, barring Roger who I don't think has any weaknesses. He'll be dishing out a lot on me."
McNamara conceded it could be an advantage - but only if the theory was put into practice.
"It's good information, it's good knowledge to have but you have to go out and apply it," said McNamara. "It's easy sitting in a video room assessing players and thinking about what you may be able to do but you have to get the players physically and mentally ready to do that."
The test kicks off at 5pm on Sunday (6am Monday NZT).
