Ramsey said the different role for Rooney would allow him more time on the ball and Wales had to make sure he did not pick them apart.
"Rooney is a fantastic player. He has great ability on the ball and a range of passing," the Wales midfielder told reporters in France. "We will have to look out for him, be wary of that. Hopefully we can keep him quiet.
"It is not an easy position for him to play but a player of his quality probably finds it a bit easier to slot into there. We defend as a team, we can drop deep and be tough to break down so hopefully that works in our favour."
