The Chelsea player will face his Manchester United opponent at Wembley in what he expects to be a close contest.
"Rooney is a key part of the England team and will be very difficult for us to stop," the Daily Star quotes Ramires as saying. "I expect a good duel with him.
"But England are dangerous from all areas because the Premier League is the best league in the world and has many stars. This is not just a friendly for us."
Meanwhile, Ramires's club teammate Ashley Cole will receive his 100th cap for the Three Lions tomorrow.
