During a recent lie detector test, Cristiano Ronaldo was asked if he would trade his Champions League medals for a World Cup victory.

The 38-year-old forward, who represents Al Nassr in the Saudi Pro League, recently appeared in a video with cryptocurrency trading business Binance where he met with a licensed polygraph examiner.

The five-time Ballon d’Or winner will reportedly be questioned about his illustrious career in the exam, according to Tineoysidro7, a content creator for Binance.

In reality, Ronaldo is questioned about the World Cup, one of the few trophies missing from his already crowded trophy cabinet, in the brief teaser video he shared on his social media accounts.

Watch that footage down below.

Although the lie detector test results have not yet been made public, Ronaldo claims it was “one of my hardest challenges yet” and that the whole footage will be available shortly.

“The test was carried out by a professional polygraph, who evaluated Ronaldo’s responses for signs of deception. The results of the test have not yet been made public,” Tineoysidro7 writes on the Binance website.

“The lie detector test is an effort by Binance to educate consumers about cryptocurrencies. The company believes that it is important that people understand the risks and rewards of investing in cryptocurrencies.

“The Ronaldo quiz is just one of the many educational initiatives that Binance has undertaken in recent years.”

Ronaldo allegedly aims to talk about his personal experience with cryptocurrency as well as his future plans in addition to career-related queries.

Rio Ferdinand, a former teammate of Cristiano Ronaldo, participated in a lie detector test last year on his YouTube channel Rio Ferdinand Presents FIVE.

He was questioned about Virgil van Dijk, Kalvin Phillips, and Erling Haaland at this point. In fact, Ferdinand was questioned by host Joel Beya if he believed Van Dijk to be a greater player than he was.

The former Manchester United center defender confidently answered “no,” but the lie detector’s supervisor gave a negative response.

Ferdinand believed he was telling the truth despite the polygraph test indicating otherwise before asserting that “no one plays” in the modern game as he used to.

“The other day, my son was watching a video on YouTube of me. It was 15 minutes long,” the former England international said. “I sat down and watched about nine minutes and I was thinking ‘no one does that. No one plays like that no more.’

“There isn’t any centre-back that I’ve seen in recent years that plays like that.”

Ferdinand added: “Virgil’s top. When his career is finished you can do this (compare).”

Joel Beya, who was interrogating Ferdinand the entire time, asserted that Van Dijk would not have six Premier League championships to his credit when he retired.

He responded, saying: “You said it. He’s the best now. He’s making it look easy.”
