The triumph saw Atletico go clear at the top of the table by four points with two games to play.
Afterwards, Koke said: "It's tiring, the truth in the end we did a spectacular job in the game.
"We were 2-0 and took a little step back at the end. We made a great effort to win beyond the very good and not so good moments that we have done, but in the end it was about adding three at a time. Two games remain, one world remains. LaLiga is very tight now at the end. For us they are finals. Today it was and we won it and on Sunday too, and we will try to win.
"We are Atleti and if we do not suffer it would not be us."
