In April 2009, China appointed Gao Hongbo as the new manager, replacing Yin Tiesheng. His arrival saw China opt for a new strategy, turning towards ground passing tactics and adopting the 4–2–3–1 formation. It was noted that Chinese footballers had relied too heavily on the long ball tactic for almost a decade. Wei Di, the chief of the Chinese Football Association, stressed that, "Anytime, no matter win or loss, they must show their team spirit and courage. I hope, after one year's effort, the national team can give the public a new image." Gao was knocked out of the 2011 AFC Asian Cup's group stage. His winning percentage (65%), the highest for a Chinese manager since Nian Weisi (67.86%), did not defer the Chinese Football Association from replacing him with José Antonio Camacho in August 2011, less than a month before the qualification process for the 2014 FIFA World Cup.
