With El Clasico approaching we look at how Luis Enrique reinvigorated Barcelona and evolved Pep's tiki-taka football.
Barcelona currently lead Real Madrid in the La Liga standings by three points, but lost this fixture 3-1 last season in October.
Three points can be viewed as a notable advantage even at this early stage of the season.
The fierce level of competitions between these teams is perhaps best reflected in the history of the fixture.
Over 170 matches, Real Madrid have won 71, Barcelona 67 with 32 draws. It remains a difficult fixture to call either way.
Who do you think will win this weekend? Real Madrid or Barcelona?
