OLLIE LAWRENCE admits he is stepping into the unknown when he takes on Australia’s rugby league superstar Joseph-Aukuso Suaalii at Twickenham on Saturday.

England centre Lawrence lines up opposite Suaalii after the 21-year-old was given his Test debut less than a month after switching to union from NRL side Sydney Roosters.

It is hoped that Suaalii will help lift the Wallabies out of the doldrums in time for next year’s British and Irish Lions tour amid predictions Down Under that he will become their most successful cross-code convert yet.
