1950/51 La Liga: Atletico bt Barca 6-4
Atleti won their fourth league title in the 1950/51 season, buoyed by a statement win in just the second round of the season.
After losing their opener against Athletic Club by a 4-0 scoreline, Los Rojiblancos needed a response when they hosted Barcelona the following week. They did exactly that.
Barça took an early lead through Marcos Aurelio after just three minutes but Atleti his five without reply through Adrian Escudero, Rafael Mujica, Duran, Henry Carlsson and Escudero to put themselves 5-1 up after 50 minutes.
There were still four goals to be scored - three from Barcelona (a Cesar Rodriguez brace and another from Aurelio) and one from Atletico's Jose Juncosa - making for an incredible final score of 6-4.

2013/14 La Liga: Barca drew Atletico 1-1
Atleti won a first La Liga title since their double-winning 1995/96 season at the Camp Nou in dramatic style on the final day of the campaign.

Although the home side went ahead in the 34th minute through an Alexis Sanchez rocket, Diego Godin headed home from a corner four minutes after the break to level the scores.
It remained 1-1, with Atletico putting in a strong defensive shift and earning a standing ovation from the Barcelona supporters.
