Erik ten Hag and Ajax dedicated their first Eredivisie title in five years to Abdelhak Nouri.
Nouri, a talented young player known as 'Appie', was left with permanent brain damage after experiencing heart failure during Ajax's friendly against Werder Bremen in July 2017.
Ajax wore a tribute to Nouri on their shirts as Ten Hag's men won at De Graafschap on Wednesday to complete a domestic double, having already secured the KNVB Beker title.
