Australia wing Drew Mitchell said full-back Israel Folau would add considerable value to the side ahead of the World Cup semi-final against Argentina.
Folau was absent for the team's controversial victory against Scotland in the quarter-final last weekend and the expectation is that he will add a completely new dynamic to the squad this week, especially under the high ball.
"Izzy is world class in that area," said Mitchell ahead of the Argentina fixture.
"He's proved that right throughout his career that it's one of the real strengths in his game. When he's back there more often than not you can rely on him getting up there above everyone and securing that ball."
Mitchell joins Folau and Adam Ashley-Cooper in a formidable back-three for Sunday's second semi-final.
