Real Madrid and Barcelona clash at the Bernabeau tomorrow, as they meet for the first much anticipated El Clásico of the season.
With Los Blancos currently sitting top of La Liga, victory over their bitter rivals could extend their lead to 6 points - with a game in hand.
Jose Mourinho's side are in sensational form, having won 14 games in a row - with Cristiano Ronaldo scoring 17 goals already this season.
Mesut Ozil and Gonzalo Higuain have also been instrumental to their sides phenomenal start, with Madrid scoring 49 goals in 14 games.
The reigning champions are also in fine form, but have struggled somewhat away from home, dropping 9 points on their travels.
The Catalans have only lost once in the last four months however, with Messi once again earning plaudits as the best in the world.
The diminutive Argentine has scored 14 goals this season, while his fellow FIFA Ballon D'or nominee Xavi has orchestrated Barca's play.
With the title potentially at stake, Saturday's El Clásico between the two best teams in the world is sure to live up to it's name.
