Ferran Torres scored the first hat-trick of his Barcelona career in a 4-2 win at Real Betis on Sunday.
He opened the scoring with a 21st-minute tap-in after being set up by Pedri.
The former Manchester City forward made it 2-0 early in the second half when he converted a rebound after Lamine Yamal had struck the post from a narrow angle.
Two fabulous finishes by Isco drew Betis level but Barca retook the lead in the 90th minute when Joao Felix found the net from 18 yards with the outside of his right boot.
Torres then wrapped up the victory for the away side in added time.
