Barcelona coach Xavi blew a fuse during defeat at home to Villarreal.
Barca lost 3-5 on the day and at 2-3 saw a penalty for handball awarded then overturned by VAR.
In reaction, Xavi turned to the TV camera and shouted, "A disgrace! A disgrace!"
Ref José Luis Munuera Montero blew for the handball after the ball struck Santi Comesaña. But the VAR later ruled it not deliberate and the ball had struck his elbow.
After the game, Xavi announced he would be leaving Barca at the end of the season.
