The Italian left Paris Saint-Germain to take over from Jose Mourinho at the Bernabeu this summer, and Ramos has been impressed so far.
"We have to forget the Mourinho period and focus on what we want to instill under Ancelotti," Ramos told reporters. "This style of play is not new to us.
"We have great players with great quality and we must adapt to the system. We have players that make a difference. A great squad."
Ramos signed for Los Blancos in 2005.
