Barcelona vs Real Madrid: 5 things to look out for in El Clasico

#2 Barcelona's final test en route to 'invincible' title

The El Clasico is the final test of Barcelona's 'invincible' credentials

Barcelona wrapped up a seventh league title of the last decade in the Spanish top-flight last weekend. But what's special about this triumph is, they did so without losing a single game. Thirty-four games played 26 victories and no defeats.

The Blaugrana are firmly on their way towards becoming the first side in La Liga history to go a whole season unbeaten. And Real Madrid are the last genuine test to their invincible credentials. Because of the remaining games, they play Villarreal and Real Sociedad at home, while interspersed in between is a facile trip to Valencia to face a 17th placed Levante.

Even if the form tips the scales in the home side's favour, Clasico is so unpredictable that the odds go out of the window. Matches can swing within a drop of a hat and no tie is really over until the whistle is blown. Barcelona's dream of 'Invincibles' hangs on this tie and this tie alone.

Avoid a defeat, and there are as good as that.
