England coach Eddie Jones has warned the Wallabies to be prepared for an "enormous scrap" when the teams clash next month in a three-Test series in Australia.
The tough talk came on the same day as powerful centre Manu Tuilagi was ruled out of the tour with a hamstring problem.
Tuilagi sustained the injury in Leicester's Premiership semi-final defeat at Saracens on Saturday and, following a scan, was told to stay at home.
Australian Jones, who named four uncapped players in his 32-man squad, made no secrets of his ambitions for the team.
"We want to be the top team in the world... therefore, if we go to Australia, we should expect to win the series," the 56-year-old told British media.
