Barcelona have won three of their last four meetings with Real Madrid since Xavi took charge of the club.
The Blaugrana have only lost once – the league fixture at the Bernabeu last October.
Barca defeated Real Madrid 4-0 win towards the end of last season, and Barca defender Ronald Araujo seems to be very pleased with that performance and result.
“It was really important for us because we were coming from a slightly tough moment and having lost various games against Madrid,” Araujo told ESPN.
“I think that [4-0] game turned things around and allowed us to say: ‘We are here, we’re on our way back.’ Now [this season], you are seeing the fruits of our hard work.
“Xavi came in halfway through last season and when you are playing so many games, you can’t [change] much. I think in preseason we were able to work a lot on a defensive level.”
