Mbappe swapped his No9 for the No10 this summer and Real's coffers are already benefiting.
According to a study by Euromericas Sport Marketing, reported by Sport, the Real Madrid jersey featuring Mbappé's number 10 achieved record sales in the first 48 hours, with 345,000 units sold.
This result surpassed all previous records, including those held by Mbappé himself wearing the number 9 and Cristiano Ronaldo. The success isn't just for the player: it's also a triumph for Real Madrid and the Adidas brand, which produces the team's kits.
The number 10, historically associated with Real's greatest champions, confirms how the choice of numbers in modern football often has a significant economic impact.
