While Graham Arnold was the caretaker coach for the Socceroos, Baan, alongside his Technical Director duties, was also briefly the caretaker coach for the Australia Under 23 team.
He was briefly appointed as a caretaker manager for the Netherlands for a 3–0 win over Cyprus in February 1981, and for Australia in 2007 for a 1–0 victory at Craven Cottage against Nigeria.[3]
He announced his retirement from his job as technical director of Australian football and his position has been replaced by Han Berger.
