Gerard Pique thought Sergio Ramos' challenge on Lionel Messi deserved a red card.

"I am sure when he gets home he will realize it was a red card," Pique told reporters.

"It was clear: he went in with both feet off the ground, nowhere near the ball. There's no argument. What happens is that [Madrid] are used to having very permissive referees here and when there isn't one, that's how they react."

Pique added that he thought Ramos' complaints after the red card were directed at him, but he didn't hear what was said.

"I didn't hear him, I saw that he was pointing at me, I suppose he was referring to the red card," the Barca defender said.

"When he gets home and sees the replay he will regret [his reaction], because it's a clear dismissal. It's a straight red card."

Ramos said that he did not regret what had happened and insisted that he felt his challenge only merited a yellow card.

On his reaction to the dismissal, he said: "I wasn't recriminating the referee for anything, no. I was talking to Pique, not to the referee. Sometimes referees get things right, other times they don't. It was a key moment. But my reaction was to Pique, not the referee.

"[Barcelona] have a way of understanding football and they always talk about the referees and maybe that ends up bearing results.

"We're not going to talk about the referees, though, that's not our style. It's not our sport. I wasn't directing [gestures] at the referee, but at Pique, who is the one who always likes to talk about referees."

Questioned on Pique's comments that referees often favor Madrid, Ramos added: "Permissive [refereeing] was their game against PSG.

"Pique likes to talk about referees. I said to him [when leaving the pitch] that with so much pressure and complaining in every tweet, it's going to end up having an effect."
