New signing Dani Olmo scored a goal in the final minutes, giving Barcelona a 2-1 win over Rayo Vallecano and a full score after 3 rounds in the Spanish League, Tuesday.
Olmo missed Barcelona's first two league matches, after the club failed to register him due to difficulties in adhering to the rules of financial fair play, set by the Spanish League.
But he came on as a substitute in the second half to give the team the spark it needed in his first appearance, after joining from German club Leipzig.
He scored the winning goal in the 82nd minute, after Pedri equalized from a counterattack in the 60th minute.
Unai Lopez, Rayo Vallecano player, opened the scoring in the ninth minute.
Barcelona leads the league with 9 points from 3 matches, two points behind Villarreal in second place, while Vallecano occupies eighth place with 4 points.
