Barcelona came from a goal down to beat Real Valladolid in LaLiga on Saturday.
The win saw the Catalans extend the gap at the top of the table to seven points ahead of Real Madrid.
But it was the relegated side that took the lead in the sixth minute of the game.
Ivan Sanchez shocked Barca, after he latched onto a through ball from Ivan Sanchez to fire past Marc-Andre ter Stegen.
Hansi Flick’s men saw their attempts thwarted by André Ferreira’s fine goalkeeping.
Ferreira denied Ansu Fati and Lopez as the visitors struggled for rhythm.
But Raphinha curled home a delightful half-volley into the bottom corner in the 54th minute after the Portuguese stopper parried Lamine Yamal’s cross.
Fermin Lopez completed the turnaround on the hour mark, firing home from a distance.
Barcelona now have 79 points ahead of second-placed Real Madrid, who host Celta Vigo on Sunday.
