(Reuters) – Dutchman Dick Advocaat has resigned as coach of Iraq after failing to secure a single victory in six World Cup qualifiers in his three months in charge. The 74-year-old, who counts three stints as Netherlands coach among his many previous posts, will be replaced by Montenegrin Zeljko Petrovic on a caretaker basis for the Arab Cup, which gets underway in Qatar next week. “The Iraq Football Association has accepted the resignation of coach Advocaat,” Iraq FA spokesman Ahmed Zamil said in a statement on Facebook. The top two in the group qualify directly for next year’s finals, while third place would offer a passage to Qatar via two playoffs. Iraq, Asian champions in 2007, have competed at the World Cup finals only once in 1986, losing all three matches.
