Lee Kang-in has yet to play a single minute for Atletico Madrid, but he is already creating a buzz in Spain. According to MARCA, the South Korean midfielder is leading jersey sales ahead of his official debut, signaling positive commercial and image prospects for the club.

Having joined Atletico Madrid from Paris Saint-Germain on a five-year deal, Lee Kang-in has taken the iconic number 7 shirt previously worn by Antoine Griezmann, who has moved to Orlando City SC. Even before stepping onto the pitch, the South Korean star has made a notable impact in the club's commercial market.

MARCA reports that Lee Kang-in's signing is the most appealing deal for Atletico in recent times. The publication states, "Lee Kang-in is the player with the highest jersey sales before debuting for Atletico Madrid." This achievement is particularly remarkable, as MARCA highlights that even a star like Julián Álvarez has not sold as many jerseys prior to officially joining a club.

The excitement surrounding Lee Kang-in extends beyond fan interest; it has also translated into significant financial benefits for Atletico Madrid. MARCA notes that this effect has resulted in increased revenue for the club. However, Atletico has yet to disclose the exact number of jerseys sold or the specific revenue generated by the South Korean international.

Despite completing his transfer, Lee Kang-in is currently unable to join Atletico Madrid due to mandatory military service obligations in South Korea. He is training separately in his home country. If all goes according to plan, his debut is expected to occur during the match against Manchester City at the Coupang Play Series on August 9.

Expectations are high for Lee Kang-in to bolster Atletico's attack in the upcoming season. Not only has he generated significant commercial interest, but he is also viewed as a key player by the club's management and fans. MARCA concludes, "The fact that Lee Kang-in has been given Griezmann's number 7 jersey indicates that Atletico Madrid expects him to play a particularly important role in the team." This suggests that the South Korean newcomer is seen as one of the most anticipated figures for Atletico as the new season approaches.
