Barca sit top of La Liga after eight games and are four points ahead of European champions Real heading into the eagerly anticipated showdown at the Santiago Bernabeu.
Real, however, currently possess the most potent attacking force in La Liga, having scored 30 goals in eight matches, with Cristiano Ronaldo alone having scored 15 in seven appearances.
"We need to keep the ball with us, that's what we want," he said on Friday.
"We want to have more possession than Real Madrid and from that point on we will try to make as few mistakes as possible and be sharp on our attacking game.
"There is no doubt that one of their bests is their capacity to score. Their capacity to score makes them one of the best teams in the world and it's a quality we can't ignore nor deny."
"Well it's totally different to go as a manager rather than as a player," he added. "One situation has nothing to do with the other.
"I barely remember what it was like to play there as my last time was many years ago. As a manager I went last year [with Celta Vigo], it was a pleasure, very quiet, I didn't have any problems."
