The red card shown to Cristiano Ronaldo during Juventus' 2-0 win over Valencia provoked a furious reaction from his sister Katia Aveiro.
She took to social media to vent her anger as her brother was sent off for a confrontation with Jeison Murillo.
"The shame of football, justice will be done," she wrote in one of a series of posts.
"They want to destroy my brother, but God never sleeps.
"They'll pay for these tears.
"They want to sink you, but they won't manage to."
