Van Basten is currently in charge of Holland but announced in December he would not be renewing his contract following the summer showpiece in Austria and Switzerland. He has agreed a four-year deal at the Amsterdam Arena which starts on July 1. Van Basten's assistants John van't Schip and Rob Witschge will also move to Ajax this summer. The 43-year-old, who had a spell coaching Ajax's reserves in the 2003/04 season, will take over from Adrie Koster who has been in caretaker charge since Henk ten Cate quit the post in October to become part of Avram Grant's backroom staff at Chelsea.
