Castellón

As a youth de León played for local side Hispania FA. At age 9 he was invited to trial with Sevilla. At the age of ten in April 2014, he was invited to Spain to participate in a trial and youth tournament for Málaga and a second training period with Sevilla. While playing for GPS Puerto Rico in the Sheffield Cup in 2019, he was spotted by the International Development Academy based in Valencia and he and his family moved to Spain to join the club in summer 2020. In winter 2021/22 de León joined the youth team of CD Castellón. After being the team's top scorer with twenty three goals in thirteen matches in the U19 league, the player attracted interest from La Liga clubs Barcelona, Almería, and Sevilla in spring 2022. Shortly thereafter he was linked with moves to Real Madrid, Atlético Madrid, and Real Betis. Despite the interest, de León signed his first professional contract with Castellón in May 2022, a two-year deal which would see him remain at the club until 2024. He made his debut for the club the same month against Villarreal B. The following month Valencia was exploring loan options for the player.
