First, what a game.
La Liga is often described as a slow, luxurious league of leisurely, technical football. Tonight was anything but in terms of speed and intensity, even for a Barca-Madrid derby.
Rather than turning that fire into confrontation, fisticuffs and unsightly physicality, tonight's game was a back-and-forth spectacle of furious attacking football from both sides. Real only needed to draw, but they tried to play a positive game, even if it was restrained by a conservative lockdown approach to protecting their lines, at least in the first half.
Barca started nervy but thanks to the quality of their match-winning individuals they managed to ride out their panic and stress to take all three points: a huge result for the Catalans who can now take control of the La Liga campaign and find new confidence in their approach and abilities.
Here are five points on how tonight's El Clasico was won, and lost, by Barca and Real respectively.
