A number of Ajax stars, including their coach Frank de Boer, have had a prank played on them by the club's kit manufacturer, Adidas.

Siem de Jong, Daley Blind, Jasper Cillessen and De Boer were led into a room by former goalkeeper Edwin van der Sar where they were met by an actor, who played the role of an Adidas representative.

He then handed them a number of shocking shirt designs and asked for their opinions. One of the designs is of a bear's face, which is printed onto the front and back of the shirt.
