Barcelona restored their four-point lead at the top of La Liga after Lamine Yamal secured victory over Athletic Club.
The Spain international curled a stunning effort past Unai Simon in the 68th minute from inside the area after latching on to a pass from Pedri at the Estadio de San Mames.
It was the 18-year-old's 19th goal of the season and continued his hot streak in La Liga after netting a first career hat-trick against Villarreal last weekend.
The victory extends Hansi Flick's side's lead at the top of the division after Real Madrid's late 2-1 win against Celta Vigo on Friday night.
Barcelona are next in action on Tuesday, 10 March (20:00 GMT) when they host Newcastle United in the first leg of the Champions League last-16.
Athletic Club, meanwhile, are back in La Liga action against Girona on 14 March (13:00 GMT).
