The Group A rivals meet in Fortaleza on Tuesday, with both entering the match off the back of victories in their opening fixtures.
"We have to cover, have two against one, be fast and reduce the spaces on the pitch - do not let [Neymar] play," he told Globo.
"It was a good win [against Cameroon] and very important. Against Brazil, it will surely be a very difficult game. We know the talent of Neymar, Oscar, Hulk but we will train in ways to handle them."
Marquez is currently taking part in his fourth World Cup.
