Born in Amsterdam, North Holland, Witschge started his professional career with local Ajax, being an undisputed starter at the age of 20 and a crucial element of the team that won the 1986–87 European Cup Winners' Cup. During three seasons, he shared teams with his sibling Richard.
After one weak final year with Feyenoord – 13 appearances, no goals – the 30-year-old moved to Utrecht, retiring in 1999 after one season with Saudi Arabia's Ittihad. In 2001, Witschge took up coaching, being named assistant of Marco van Basten and John van 't Schip at the national team in 2004; he rejoined the pair at Ajax four years later, again as assistant.[1]
