Barcelona secured two late goals to beat struggling Rayo Vallecano in a remarkable game, extending their lead at the top of La Liga to four points.
Luis Suarez put Barca ahead from Jordi Alba's cutback, but Jose Pozo equalised with an excellent 25-yard shot.
Substitute Alberto Garcia tapped home with his first touch as Rayo looked set for a second La Liga win of the season.
But Ousmane Dembele's sweet half-volley and Suarez's last-minute strike turned it round once again.
Barcelona are now four points above Atletico Madrid, who drew 1-1 at Leganes on Saturday afternoon, and Alaves, who visit Eibar on Sunday (11:00 GMT).
For a long time it looked as though they were going to suffer a first defeat against Rayo Vallecano since 2002 - but they have now beaten them for the 12th game in a row.

With Barca on the ropes, centre-back Gerard Pique played as an auxiliary forward and headed a cross into Dembele's pass for a late equaliser - before Suarez stabbed home Sergi Roberto's deep cross at the back post in the final minute.That was his fifth goal in two games, having scored a hat-trick last Sunday in the 5-1 win over Real Madrid, and it means Barca have now won five games in a row in all competitions.
