Barcelona dropped their first points in La Liga this season as Rayo Vallecano fought back to secure a 1-1 draw at home to the champions in a testy encounter where a faulty Video Assistant Referee (VAR) system caused controversy.
Rayo substitute Fran Perez thrashed home a 67th-minute equaliser as he stole in unmarked at the back post from a corner after Lamine Yamal’s 40th-minute penalty had put Barca ahead on Sunday.
A malfunctioning VAR ensured the game was clouded in controversy after Pep Chavarria’s challenge on Yamal, which led to the spot kick being awarded, could not be reviewed because the system was not working at the time.
Chavarria did make contact with Yamal’s thigh, but the penalty award might have been overturned on review.
Both teams had been informed of the faulty system
