Barcelona entertain arch-rivals Real Madrid at Camp Nou on Saturday in a Clasico that could well have major ramifications in the race for the Liga title.
Third-placed Madrid head to Catalunya knowing that defeat will see them slip 13 points adrift of defending champions Barca, a difference that could prove too difficult to close in the seven subsequent fixtures.
Here, courtesy of Opta, we take a look at the key statistics ahead of the resumption of one of football's greatest rivalries:
0 - Barca have never won a league game against Real Madrid when top of the competition and holding an advantage of 10 points or more (D1 L2).
1 - Barca have lost just one of their last seven league games at home against Madrid, winning five. Their only defeat in that run was a 2-1 loss in April 2012.
3.22 - In 171 matches between the two sides, the average of goals scored per game is just higher than three, though the most common result is 2-1 to Real Madrid, which has occurred 18 times previously.
4 - The last four red cards in matches in all competitions between the two teams were all shown to Madrid players.
