Nadal was spotted wearing a fake jersey while celebrating Spain's World Cup victory.

Rafael Nadal is a passionate football fan who has always held great affection for the Spanish national team and Real Madrid.

Rafael Nadal joined in the fervent atmosphere when the Spanish team defeated Argentina 1-0 in the World Cup final at MetLife Stadium to become world champions for the second time. However, instead of focusing solely on the tennis legend's celebration, netizens paid special attention to... the jersey he was wearing.

Right after the final whistle, Nadal shared a video capturing the moment he celebrated with family and friends at home. Earlier, the former world No.1 also appeared on a TV show wearing the white Spanish national team jersey to support La Roja in the final.

Just minutes after the image spread, social media was flooded with comments suggesting that Nadal's jersey might not be an authentic version. Many fans analyzed details such as the badge, sleeve patches, and certain design elements, concluding that it could be a fake jersey rather than an official product.

So far, there has been no confirmation about the authenticity of the jersey. Nevertheless, the story quickly became a hot topic on social media platforms, sparking many humorous comments.

What surprised many people is that Nadal is one of the most successful and wealthiest athletes in tennis history, with numerous lucrative sponsorship deals. Therefore, the theory that the "king of clay" wore an unofficial jersey created an interesting contrast and drew public attention.

Spanish journalist Jose Moron also joined the debate. According to him, what is noteworthy is not only whether the jersey is authentic, but also the fact that Nadal appeared in an Adidas-branded product while he had been associated with Nike for most of his playing career.

Moron argued that if the official jersey was sold out in the market, it would be understandable for fans to choose an alternative version. He also questioned whether Rafa is still bound by Nike's promotional terms after his retirement.

Before the final, Nadal expressed his excitement on social media, recalling the moment Spain first won the World Cup in 2010 in South Africa. The 22-time Grand Slam champion affirmed that football has always been one of his greatest passions since childhood.
