Celta Vigo are still looking for their first home win of the season in La Liga after a 1-0 loss at the hands of Elche.
Manu del Moral should have given the away side the lead with just four minutes on the clock, but Yoel made a good reaction save from close range.
Celta's best chance of the first half came when Manu Herrera fumbled a cross, but the goalkeeper redeemed himself with a good save from Charles's shot.
In a match of few chances, it took a moment of brilliance to break the deadlock. Javi Marquez strode forward with the ball from midfield and finished calmly to give his side a 72nd-minute lead, which proved to be crucial.
