Fermin Lopez scored twice as Barcelona came from behind to defeat Atletico Madrid 2-1 and move three points clear at the top of La Liga after 12 games.
Giuliano Simeone put Atletico ahead in the 10th minute with a close-range volley from Julian Alvarez's cross. Lopez equalized just before halftime after the ball broke to him in the box.
Lamine Yamal set up Lopez's second goal in the 66th minute with a pass. Lopez finished first-time past Jan Oblak to secure the win.
Barcelona now leads Real Madrid by three points and Atletico by five. The victory marks Barcelona's fifth straight away league win over Atletico.
"It was a very difficult match," Lopez told La Liga TV. "The first half was tough, but we managed to come from behind and secure the win. Lamine has been very good. His pass for the second goal was half the goal itself. I think the team produced an incredible second half, both defensively and offensively."
