Ajax handed Feyenoord their second defeat of the season on Wednesday as they beat the Rotterdammers 1-2 in De Kuip to reach the KNVB Cup final, where they will face PSV. Dusan Tadic, Santiago Gimenez, and Davy Klaassen scored the goals, but the main story of the night was Davy Klaassen being hit by an object thrown by a fan.
