Two goals in the first five minutes put Atletico Madrid on track for a comfortable 5-1 win at Las Palmas on Saturday.
Diego Simeone made five changes to the side which drew 2-2 in last weekend's opener at Girona, and his side were 2-0 up inside five minutes thanks to neat finishes from Angel Correa and Yannick Carrasco.
Ex-West Ham striker Jonathan Calleri headed the home side back in the game near the hour mark.
But midfielder Koke soon restored his side's two goal advantage with a fine 25-yard strike, and the Atletico midfielder then got his second of the night with a spectacular bicycle kick.
Atletico goalkeeper Jan Oblak saved Jonathan Viera's penalty before young midfielder Thomas Partey rounded off the scoring late on.
The defeat was the second consecutive loss for Las Palmas to open the season.
