Kjell Scherpen: New Ajax signing made to write lines in joke video
As far as punishments are concerned, bans or fines are usually the norm for footballers.
They like to do things differently at Ajax, however.
Most people were at school when they were last told to write lines...
But not Ajax's new signing Kjell Scherpen who, at the age of 19, was ordered to write "Ajax is the most beautiful club in the Netherlands" 1,000 times.
There was no time to mess about, either. Ajax's chief executive Edwin Van der Sar and football director Marc Overmars were keeping a watchful eye over the young goalkeeper.
Scherpen's boyhood club is Feyenoord - Ajax's fierce rivals. When it was announced this month he would join the club in June from FC Emmen, Ajax fans weren't happy.
It was discovered that Scherpen had bad-mouthed Ajax on social media in 2011, saying the club were "lucky".
Let's hope he has learned his lesson.
