The 31st round of the Primera Liga is likely to be decisive. Real beat Leganes 4-2 on Saturday to continue unbeaten since January 15 when he lost 2-1 to Sevilla.
Since then, the Meringi has won five consecutive victories, the same as the winning trophy for the Rojiblancos, who finally managed to climb to third place in the Liga, their best position in the current season.
Atletico will face the loss of a three-point lead at home to Vicente Calderon, who will replace him at a new stadium later this season. If they do not face the Champions League, the fans will remember the last derby on the pitch.
Luis Enrique's Barcelona, which has been performing quite differently since their big uphill battle against Paris St Germain in the Champions League final, is preparing to take Malaga's place at La Rusalida.
The match comes after Malaga won the 30th round of the league on Saturday at the expense of Sporting Gijon for the first time since Jose Miguel Gonzalez "Mitchell" took over as Uruguayan coach Marcelo Romero.
The Real Madrid lead is currently ranked 71 points, two points behind Barcelona and ten on Atletico who is third
