Without many frills in attack, with hardly any effective pecking, but with obvious defensive strength from goalkeeper Aaron Ramsdale and defenders Ben White and Aaron Saliba, Arsenal beat Crystal Palace 0-2.
After caressing the Champions League last season, Arsenal, again, for the third consecutive year, was in charge of opening the competition.
Renewed, with flashy signings such as Gabriel Jesús or Aleksandr Zinchenko, Mikel Arteta's team had a winning aroma after completing a good preseason in which they showed a good level with which the 'Gunners' fans were filled with hope.
Arteta did not hesitate to line up both Zinchenko and Gabriel Jesús. Also to Saliba, who returned from his loan at Marseille and found a place in the center of defence. And, with three of their seven new faces on the pitch, Arsenal posed a clash of football control.
Arsenal, with almost absolute dominance, went into the break ahead on the scoreboard.
Gabriel Jesús was a real nuisance for the Palace defense, unable to stop the Brazilian, very clever with accurate movements from behind with which he generated many gaps.
The Arsenal goalkeeper saved the tie and Crystal Palace, who smelled blood, did not stop insisting, pressured by the passage of time.
However, between White and Saliba, both immense, they closed any door to a comeback for Palace, who received the final straw, five minutes from time with Marc Guehi's own goal after poorly clearing a poisoned Saka cross.
