Former Holland manager and striker Marco Van Basten has quit his role as FIFA's chief technical development officer, claiming he wants to spend more time with his family.
The 53-year-old, who enjoyed a glittering playing career with Ajax and AC Milan before moving into coaching, joined FIFA's technical team in 2016.
Van Basten was one of FIFA's key advocates for video assistant referees but he had less success with ideas for several radical changes to the game's laws. These included scrapping extra-time and offside, sin bins instead of yellow cards and ice hockey-style one-on-ones instead of penalties.
In a statement, Van Basten said: "After two good and interesting years I decided to put an end to my duty at FIFA, mainly to be able to spend more time with my family in Amsterdam.
"I learned a lot being in a position to influence this game from the other side. The World Cup in Russia with the introduction of VAR was a nice milestone."
FIFA's deputy general secretary Zvonimir Boban thanked Van Basten for his work in "reconnecting the institution with its technical community" and wished the Dutchman all the best for the future, which may include future projects with FIFA.
FIFA is set to publish the last piece of work that Van Basten oversaw, the technical report on tactics at the World Cup this summer, on Tuesday.
