“The team needed this victory. It keeps us near the top and close to reaching our goal,” Sevilla midfielder Joan Jordan said. “It was a special game for our fans. It’s always good to win a derby.”
En-Nesyri scored the winning goal with an angled shot from the right side of the area after getting past the goalkeeper inside the box.
Sixth-place Betis, which had a goal disallowed for offside in the 72nd, had won four in a row in the league. It could have moved within three points of Sevilla with a win. Betis trails Sociedad by three points.
Atlético Madrid saw its lead cut to six points on Saturday after it drew 0-0 at Getafe and second-place Real Madrid rallied to beat Elche 2-1 at home.
Barcelona can move within four points of Atlético if it beats last-place Huesca at home on Monday.
SOCIEDAD’S RUN HALTED
Granada ended Real Sociedad’s seven-match unbeaten streak with a 1-0 win thanks to Germán Sánchez’s second-half winner.
The result moved Granada to eighth place and left Sociedad in fifth. The Basque Country club had entered the match with a chance to overtake Sevilla for fourth in the final Champions League qualification spot.
