After Niklas Moisander departed the club at the start of the 2015–16 season, Ajax manager Frank de Boer decided to choose Riedewald as the new partner of Joël Veltman in central defense.
In de Klassieker against Feyenoord on 7 February 2016, Riedewald got injured soon after kick-off; he had broken his left ankle, which meant his season was finished.
Until that moment, he had only missed one league game due to suspension.
He returned early from injury on 1 May 2016, replacing Kenny Tete in the 76th minute in a match against FC Twente.
