Mora enters the match trailing legends like Pelé, Samuel Eto'o, and Norman Whiteside, who also made their World Cup appearances before turning 18.
Modern icons Lionel Messi and Cristiano Ronaldo made their tournament debuts at ages 18 and 21, respectively.
"Like Lee Kang-in, I also started my career at a young age, but I will strive to show my best skills in tomorrow's match," Mora said.
With Mexico seeking a decisive result in Group A, Mora remains eager to test his skills against top-tier international talent.
"I will go onto the field and enjoy soccer. Whatever playing time I am given, I intend to enjoy it.
Facing a great player like Lee Kang-in is an exciting thing. I always enjoy clashing and fighting against the world's best players," he concluded.
