The defender made clear that collective work and concentration are key to containing the England striker, who found the net on his Euro 2012 debut against Ukraine
The Manchester United striker appeared in his first game of the tournament against Ukraine, and netted the winner as the Three Lions secured top spot in Group D with a 1-0 victory.
Barzagli praised the qualities of Rooney, but insisted that his team will be capable of containing the 26-year-old international on Sunday.
"As a team we can stop him, we are four at the back, so an effort from the entire team is needed," the Juventus defender told reporters at the pre-match press conference.
"We know just how good Rooney is and how England are as a side. We need to be 100 per cent focused to counteract this player.
