The return leg of an Olympic Games Football Tournament qualifying match between Vietnam and Afghanistan has been cancelled due to security fears in the Afghan capital Kabul, the Asian Football Confederation has announced. An AFC official told there would only be one leg in this preliminary round because of security concerns. Vietnam coach Alfred Riedl confirmed his team would not travel to Afghanistan. "The AFC said there was a security problem and we did not need to go there. We heard Bangkok would stage the match but then they decided against it so that is much better for us," Riedl told Xinhu.
