Through 25 games, Barcelona has seen its mid-season lead diminish as Real Madrid closed within four points of its bitter rival this weekend win a win at Espanyol on Saturday.
Meanwhile in Madrid, Barcelona couldn't manage to come away with a win over recently ailing Atletico Madrid, dropping the three points in a 3-4 loss.
Two goals from Argentina-native Sergio Aguero, including a late dagger in the 88th minute, helped put away the Catalan giants.
After having a significant lead in the table halfway through the current campaign, Barcelona have had a tough run of luck having not won in league play since a 3-1 home victory over Sporting Gijon.
Madrid, on the other hand, is playing their best football of the season and are currently riding a 10-game winning streak in the Primera Liga. The last match they surrendered was against Barcelona all the way back in mid-December.
The remainder of the table finds itself at least nine points behind second-place Real Madrid with Sevilla and Villarreal rounding out the top four spots.
Sevilla picked up a much-needed victory Saturday with a 2-1 escape over Athletic Club Bilbao to bring their point total to 47.
Valencia had another tough weekend losing 1-2 at home to Valladolid. They finished the week with the same point total in which they entered it, providing reason for concern after dropping behind Villarreal to sixth-place in the standings on goal differential.
