Chelsea winger Juan Castillo has completed his season-long loan move to Dutch giants Ajax.

The 19-year-old has played most of his football for Chelsea development squad and Under-19s, helping the latter team to the UEFA Youth League final in each of the past two campaigns.

Since his move to London, Castillo has represented the Netherlands up to Under-19 level and helped the London club’s Under-18s win a number of trophies, including back-to-back FA Youth Cups in 2017 and 2018.

He originally joined the Blues from the Dutch champions in 2016.
