The Dutch defender reunited with Frank de Boer in July 2017 at Palace, after the Eagles boss gave him his first-team debut in 2013 at Ajax.
Having progressed through the Amsterdam club’s academy when it was headed by De Boer, the 20-year-old played 93 times for Ajax, scoring three goals, and claimed one Eredivisie title in the 2013-14 season. He also featured for Ajax in their Europa League final defeat to Manchester United in May 2017 which proved to be his last appearance for the club.
Capable of playing at centre-half, left-back or as a defensive midfielder, Riedewald has won three international caps for Holland, having previously represented his country at various age group levels.
He was handed his first full cap against Turkey in September 2015 in a Euro 2016 qualifier, and would appear twice more towards the end of the unsuccessful qualifying campaign for the Dutch.
