Sergio Ramos has once again managed to steal headlines following Real Madrid's 2-1 win over Ajax in the first leg of the Champions League last 16.

Goals from Karim Benzema and Marco Asensio sealed victory for Los Blancos, yet it was their captain's actions in the 89th minute and subsequent comments that have taken centre stage.

Ramos, who was on a yellow card heading into the game, earned another booking for a late challenge on Kasper Dolberg. He will miss the second leg next month.

Suspicions were immediately raised that the Spaniard deliberately got himself yellow carded in order to have a clean record for the quarter-finals and he suggested as much after the game.

"Looking at the result, I'd be lying if I said I didn't force [the booking]," Ramos told reporters after the game. "It is not to underestimate the opponent nor to think that the series is over.

"But in football you have to make tough decisions."

Aware that he had said the wrong thing, Ramos then backtracked on social media by insisting he didn't get booked on purpose.

"I want to make it clear that I have not forced the card, as I did not against Roma in my previous Champions League match," he tweeted.

"I will support from the stands as one more fan with the illusion of being in the quarters."

No one is buying Ramos' claim, though, and now UEFA themselves have responded with a statement saying they're going to investigate the incident.

If Ramos is found guilty, he will face a two-match ban.

"A disciplinary investigation has been initiated based on Article 31(3) of the UEFA Disciplinary Regulations in connection with the statements made by Real Madrid player Sergio Ramos in the above-mentioned match," UEFA said, per Goal.

"Information in respect of this investigation will be made available in due course."

Ramos could be in big trouble and Real will pray that UEFA decide there was no wrongdoing, otherwise their captain will also be absent for the first leg of the quarter-finals.
