Atletico travelled to Valladolid on the final day of the La Liga season last Sunday.
Simeone's men needed to win or Real Madrid not to beat Villarreal. Valladolid took the lead after 18 minutes through Oscar Plano, but Atletico came fighting back in the second half. Angel Correa levelled in the 57th minute and then Luis Suarez capitalised on a defensive error 10 minutes later to complete a 1-2 win. The result relegated Valladolid and meant Real Madrid's 2-1 victory over Villarreal was in vain.
It was Atletico's first La Liga title for seven years and you can take a look at footage from their trophy celebrations in the video above!
