The Kangaroos want to win the Four Nations crown back and re-establish themselves as the number one team in the world.
Mansour describes England as a threat, but also as a team with “a lot at stake”.
“I think they’re obviously going to be one of the best teams in the competition,” he said.
“The Wayne Bennett factor, they’e got a lot of classy players. they’ll play with a lot of national pride and belief in their team.
“They’re definitely going to come out fighting and they’ll be scratching and clawing until the final minute of every game.
“There’s a lot at stake for them. The pressure’s on them on home soil.”
Mansour made his Australian debut two years ago in the Four Nations against New Zealand at Suncorp Stadium, with the green and gold defeated 30-12 by the Kiwis.
Since then the 26-year old has played for NSW in State of Origin and established himself as one of the NRL‘s best wingers.
Mansour said the Kangaroos want the number one ranking back.
“Everyone expects us to be the number one team in the world,” he said.
“In syaing that we really want to strive for it. Everyone’s got a lot of belief and confidence in their ability in this team.
“I believe we’ve got the best players in the world.”
