Antoine Griezmann was on target with the only goal of the match as Atletico Madrid took all three points from their La Liga curtain raiser against newly promoted Las Palmas.
All eyes were on £25 million signing Jackson Martinez on his competitive debut for the club, but it was the familiar face of Griezmann who quickly took centre-stage at the Vicente Calderon.
He won the free-kick which led to the opening goal, his powerful effort taking a small deflection off a Las Palmas player and flummoxing goalkeeper Raul Lizoain on its way into the net to secure the 1-0 win.
Deportivo La Coruna and Real Sociedad shared the spoils in their opening game of the season after playing out a 0-0 draw at the Riazor.
Real Sociedad edged the first half, creating marginally more chances. Big money summer signing Jonathas de Jesus attempted a bicycle kick that went several feet wide of goal, and then the Brazilian was put through one-on-one with goalkeeper German Lux, but the Argentinian came out quickly to prevent the striker chipping the ball over his head.
Deportivo debutant Fede Cartabia gave the hosts a greater creative outlet despite only coming on for the remaining 17 minutes. He struck wide from distance and then hit a free-kick against the wall and the rebound into the side netting.
Deportivo will perhaps feel they should have taken advantage of their superior play in the second half, while David Moyes might have felt a sense of deja-vu, as he witnessed a repeat scoreline of his first game in charge of Real Sociedad last season.
Espanyol got off to a winning start as Salva Sevilla's early goal proved enough for a 1-0 win over visitors Getafe, who had Argentine defender Santiago Vergini sent off late on.
With less than three minutes on the clock, winger Sevilla lifted a free kick over the wall and in off the post to give the hosts the lead.
The Catalans failed to build on their early advantage, however, and struggled to create more chances in the first half, while Getafe tried to hit back through a couple of shots from Pedro Leon, but the former Real Madrid man failed to hit the target.
Sunderland loanee Vergini picked up his first yellow card at the start of the first half for a deliberate handball and was then given his marching orders in the 83rd minute for bringing down Espanyol debutant Gerard Moreno.
Champions League hopefuls Valencia were held to a disappointing draw at Rayo Vallecano in an exciting yet goalless clash in Vallecas.
Nuno Espirito Santo's side had the better of the first half and came within inches of grabbing an injury-time winner when former Rayo striker Alvaro Negredo's powerful effort was tipped away by the excellent Tono.
