Antoine Griezmann's free-kick in the first-half gave Atletico Madrid the solitary goal they needed to down Las Palmas on their 66th-anniversary in the opening game of the season at the Vicente Calderon.
The 2013/14 La Liga champions were the better team throughout but often lacked the final touch to put away their opponents and in the end the home side were lucky to escape with all three points as the visitors hit the post twice.
Nonetheless, with Atletico enjoying a good summer transfer window and looking to emulate their success two years ago, they will take solace in the victory especially considering their 2014 title win was built on a succession of 1-0 wins.
Their latest 1-0 win came from last season's top goalscorer with 22 goals, Griezmann. The Frenchman was fouled by former Wigan Athletic and Everton defender Antolin Alcaraz and got up to bend in a free-kick from 25-yards which admittedly it took a wicked deflection along the way.
The duo back at the club after spells at Chelsea (permanent) and Porto (loan) were constant menaces throughout the match.
The Brazilian in particular showed he had lost none of his mojo after a stint on the bench of the Premier League champions last season as he nearly scored twice: the first effort in the 39th-minute when he dragged his shot wide from the edge of the box. The second in the 78th-minute when he went on a slalom like run on the left wing which ended with him having a shot from a difficult angle saved.
With Madrid not putting chances away Las Palmas, who were finally promoted after three consecutive seasons in the play-offs, grew into the match and hit the post for the first time after David Simon made a late run into the box and headed his effort onto the woodwork and onto the roof of the net from a free-kick.
The 72nd-minute saw Aythami's header diverted onto the foot of the post by former Benfica keeper Jan Oblak who otherwise had little to do.
That chance was the last serious effort on goal the visitors had and ensured Atletico Madrid would continue a fine tradition of not conceding at home in the opening fixture of the season.
Other debutants for Atleti included Jackson Martinez (who had a quiet game) and Angel Correa who had joined last season but missed the entire campaign due to a heart condition.
The 20-year-old Argentine had a fine cameo from the bench but the same could not be said for Fernando Torres who messed up a great opportunity in the 75th-minute after Gabi put him clear and then was booked for simulation in the 84th-minute after making the most of contact inside the box.
Towards the end Koke could have settled the game with a free-kick that hit the outside of the post. Nonetheless, the home side held on to be victorious and extended their unbeaten record over Las Palmas to 17 games at the Vicente Calderon.
