Juan Castillo is a defender or midfielder currently playing in Chelsea's Academy team.
Juan joined Chelsea from Ajax as a 16 year-old.
Juan's Chelsea career began tentatively, being used as a bit-part player in the first half of the season as he settled into a new country and a new club. As Jody Morris began to utilise a 3-4-3 formation more often as the campaign went on, Castillo became a force as the left wing-back in that setup, turning in influential performances that helped the club towards a treble success in the Southern section, the Merit Stage, and the FA Youth Cup.
He became a regular in the Development Squad thereafter, and helped Chelsea to back-to-back Finals in the UEFA Youth League, before joining former club Ajax on loan for the 2019-20 season. Despite the Amsterdam side having the option to buy him outright, they declined that option in June 2020.
Juan has represented the Netherlands up to Under-20 level. He is also eligible to represent the Dominican Republic.
