Ramos saw his captain Raul hit two goals, with Arjen Robben also chiming in, for a 3-0 victory over the Russians.
"The victory will be very good for team morale," smiled Ramos. "They worked and made an effort to produce an entertaining performance, showing a great attitude and pleasing the public.
"The negative is the fatigue, there are three days in six games. This triumph is good for the El Clasico."
Ramos added: "We'll go with maximum confidence to the Nou Camp, when we are at peak performance we can beat anyone at any stadium. Barca is a difficult team but we are capable of getting a good result."
