Edgar Davids declared he was "proud" to be reunited with Louis van Gaal after being appointed assistant coach of the Netherlands national team.
Dutch great Davids will step into the role immediately and is set to be heavily involved in the lead-up to, and throughout, the World Cup later this year.
The 49-year-old, who was nicknamed 'Pitbull' by Van Gaal when the pair worked together at Ajax in the 1990s, has taken over from Henk Fraser who is leaving to become head coach of FC Utrecht.
Davids said: "I am not only proud but also very enthusiastic that I can continue my career as a coach together with such a renowned coach as Louis van Gaal and that I can work with the absolute best of the Netherlands."
