According to the Spanish media "As", Barcelona believes that Yamal's No. 10 jersey will break the jersey sales record maintained by Messi, and may even exceed 20%-25%.

As said that in principle, on July 13 local time, the 18th birthday of Yamal, his new jersey number will be announced. All clues point to a number, and Yamal will take over the legendary No. 10 jersey, as Yamal himself has proactively promoted through social media in recent weeks. However, at present, there are only a few people in the club who know exactly what number Yamal chose in the end.

The situation is special. Ass reported that employees of the official Barcelona store received instructions to inform the customer of the current situation before selling the jersey with the name Yamal to the customer. Customers will be informed that the final number has not been determined yet, so if you choose to print No. 10 or 19, it means that you have to bear the risk that the number may not ultimately be the player's true number, and "if the printed number does not match the number finally selected by the player, no return or complaint requirements will be accepted."

Internal source of Barcelona's market department said: "If you print the wrong number, you have to bear the consequences yourself."

Ass said that local fans can wait for an extra week to wait until Yamal announced the number, which has more room for foreign tourists who only stayed for a short time. But it is understood that many tourists accepted the club's conditions and decided to take the risk and print the No. 10 directly. The club confirmed: "Now no one has printed No. 19 again."

The Barcelona market department is very clear that once Yamal's new jersey number is officially confirmed, the sales of the new jersey will usher in explosive growth, and if the final choice is No. 10, the growth will be even worse.

As reported that Barcelona executives confirmed: "We are talking about the most-selling jerseys in club history, and what we are talking about is likely to be the record that is still maintained by Messi, 20% or 25% higher than that."
