Ajax cruised into the semi-finals of the KNVB Beker on Thursday evening with a 4-0 win at Vitesse Arnhem.
Danny Hoesen set the Eredivisie champions on their way with a seventh-minute opener and Lasse Schone gave the visitors breathing space just before the hour.
Kolbeinn Sigthorsson was then introduced as a 75th-minute substitute, in place of the injured Siem de Jong, and notched a late brace to add gloss to the scoreline.
His first came in the 81st minute when he followed up after Schone had missed a penalty, and the second arrived in the form of a header five minutes later.
The result saw the Amsterdammers avenge Sunday's 3-2 Eredivisie loss against Fred Rutten's side, which ended their eight-match unbeaten run.
Frank de Boer's team joined AZ Alkmaar, PEC Zwolle and holders PSV Eindhoven in the last four.
