If England sensationally oust Australia from the Four Nations tournament tomorrow, their success can be traced back to the NRL.
Ahead of their crucial clash at Melbourne's AAMI Park - which the Kangaroos must win to remain alive - England coach Steve McNamara says he has learned a lot about the opposition from his season as a Sydney Roosters assistant coach.
He joined the NRL club after England lost a heart-breaking World Cup semifinal to New Zealand last year and is hoping the new-found knowledge leads his team to their first win over Australia in almost 20 years.
England also have six NRL players in their squad: James Graham (Bulldogs), Gareth Widdop and Mike Cooper (St George Illawarra), Sam Tomkins (Warriors) and powerhouse twins Tom and George Burgess, who helped steer South Sydney to the NRL premiership along with their rugby-bound older brother Sam.
"There's quite a few of our players who play in the NRL and all of our opposition do," McNamara said.
