Lee Kang-in, who has transferred to the prestigious Spanish professional football club Atlético Madrid, has delivered his first greeting to fans in fluent Spanish.

Having grown up in Spain since his youth, Lee shared his thoughts on the transfer for the first time through social media in fluent Spanish.

["I am truly happy to join a big club. I want to quickly put on the Atlético kit and enjoy this new adventure together with the fans. Let's go, Atlético!]

Lee also left a farewell message to his former club, Paris Saint-Germain, saying, "It was an honor to share the club's glory, and I will keep Paris in my heart."

After recharging for nearly a month following the World Cup, Lee will meet domestic fans through a pre-season match held in Seoul on August 9.
