Fabregas is adamant Barcelona will go to Madrid and attack despite the fine form of Real.
"The team is in good shape and will go to the Santiago Bernabeu looking for a win, and whatever happens, there'll be no lack of bravery and courage to play our own style," Fabregas said to Barca TV.
"If we go there with nerves or thinking we'll sit back and see what happens, we could be punished as the Bernabeu is a very dangerous place to play.
"Obviously they'll go all out for a win, and the home fans will make their presence felt. We know that if Real Madrid win, it could have a serious impact on the league. We'll go there to win. We're not afraid."
