Giminez own-goal ends Atletico's unbeaten start
Jose Maria Giminez's own-goal dealt Atletico Madrid its first defeat of the LaLiga season as it lost 1-0 to Real Betis.
Having won 10 of its previous 15 visits to Estadio Benito Villamarin, Diego Simeone's side was outclassed as it lost pace with the early leaders in the competition.
The decisive moment in the contest came in the fourth minute when Giminez deflected Abde Ezzalzouli's cross beyond Jan Oblak to hand the hosts a perfect start.
Betis looked to increase its lead before the break with Ezzalzouli striking the woodwork, while Vitor Roque also spurned several glorious opportunities.
Manuel Pellegrini's side continued to dominate proceedings, but struggled to find a second goal, with Roque seeing his effort ruled out for offside after the break.
Visiting substitute Angel Correa was twice denied by the woodwork late on, with the Argentine first hitting the post before cannoning an effort off the crossbar.
Atletico now sits fourth in the standings after 11 games of the season, 10 points behind leader Barcelona after its stunning win over Real Madrid in El Clasico.
