The versatile defender received his marching orders in the second half, but did not leave the pitch before telling the man in black how he feltReal Madrid defender Sergio Ramos insulted him after the Spain international was shown a red card in the Blancos' 4-0 Copa del Rey win over Celta Vigo at the Santiago Bernabeu on Wednesday.
Ramos was handed a second yellow card for kicking out at Augusto Fernandez in the 73rd minute of the encounter, and the 26-year-old verbally attacked him before walking off as he felt he was being treated unfairly.
"You're a crook. You have been trying to f*** us all game long," the defender repeatedly said to the referee, according to his post-match report.
The centre-back then went on to insult the fourth official, too, before making way to the dressing room.
"On his way out, he approached the fourth official, saying: 'It's the same as always you scoundrels.'"
Meanwhile, Ramos has acknowledged that he verbally attacked the referee after his dismissal.
"I am disappointed with the red card. I know this referee for quite some time now and I have never had a good feeling about him.
"Sometimes you say things in the heat of the moment that you shouldn't say. I apologise for that."
Madrid qualified for the quarter-final of the competition following Wednesday's victory, after losing the first leg 2-1.
