The Premier League giants disclosed that Castillo would spend the rest of this season at ADO Den Haag after ending his loan deal with AZ Alkmaar.
Chelsea stated this on Monday in a statement via its website ahead of their Premier League tie with Fulham on 16 January 2021.
“Juan Castillo has ended his loan with AZ Alkmaar and will spend the rest of this season at ADO Den Haag,”
The Dutch left-back returned to his homeland in October with AZ Alkmaar, where he made his top-flight debut last month in a 2-2 draw at Utrecht, and now joins fellow Eredivisie side ADO Den Haag on loan until the end of 2020/21,” Chelsea’s statement read.
Castillo joined Chelsea from Ajax in the summer of 2016.
The Dutch youngster helped Chelsea’s academy win the Under-18 Premier League and FA Youth Cup during his first year with the Blues.
