Sergio Ramos has been charged by UEFA for "receiving a yellow card on purpose.”
Ramos is accused of picking up a deliberate yellow card in the 89th-minute for Real Madrid in their Champions League last-16 first-leg against Ajax.
Real won the match 2-1 but, afterward, Ramos told reporters: "Looking at the result I would be lying if I said it wasn't intentional.
"It's something I was thinking about, it's not to underestimate the opponent nor say the tie is over but in football you have to take difficult decisions so I decided to do it."
Ramos will be banned for the second-leg against Ajax.
However, he could now miss a further two games for his actions.
Following his comments to reporters, Ramos moved to clarify what he meant.
“In a game there is always a lot of tension and you have to take decisions in seconds," he wrote on Twitter. "The best thing about tonight was the result, the worst that I will not be in the second leg due to one moment in the game.
“I want to make it clear that this hurts me more than it would hurt anyone, I did not get the yellow card on purpose, just like the last yellow card I got in the competition, and I will be supporting from the stands like any other fan hoping we get into the quarter-finals.”
UEFA's Control, Ethics and Disciplinary Body will hear the Ramos case on Thursday and decide how to punish the Real Madrid captain.
Only last week, Valencia's Geoffrey Kondogbia was handed a two-match ban by UEFA for being deliberately booked in the Europa League first leg against Celtic. The Frenchman was booked for delaying a free-kick.News Now - Sport News
