Gao was sent to a closed camp for a three-day grilling by senior officials in February with three other candidates; temporary caretaker Yin Tiesheng, 2004 Olympics boss Shen Xiangfu and former Shanghai coach Wu Jingui.

Serbian Vladimir Petrovic was the last full-time coach but his contract was not renewed after China was eliminated from the qualifiers for next year's World Cup in South Africa.
A formal confirmation of Gao's appointment is likely to come next week, with his first task to lead the squad through the 2011 Asian Cup qualifiers.
