Summer Olympics, Petrović was sacked as the manager and Yin Tiesheng was announced as the team's caretaker. 2010–present: stagnation Gao Hongbo era 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. Appointment of José Antonio Camacho On 13 August 2011, José Antonio Camacho was appointed as the new manager of the team, signing a three-year deal for a reported annual salary of $8 million. Wei Di, CFA chief, explained the decision as being part of a long-term plan to help the country catch up with rivals Japan and South Korea. He noted that, "Compared with our neighbours Japan and South Korea, Chinese football is lagging far behind, we need to work with a long-term view and start to catch up with a pragmatic approach. A lot of our fans expect China to qualify for the 2014 World Cup finals in Brazil. They are afraid that changing the coach at the last moment may cause bad effect to the team's qualifying prospect. I can totally understand that. But we do not have any time to waste." Yu Hongchen, the vice-president of the Chinese Football Administrative Centre, also stated, "The qualifying stage of 2014 World Cup is just a temporary task for him. Even if the task is failed, Camacho will not lose the job. When we started to find a new coach for the national team, we mainly focus on European countries such as Germany, the Netherlands and Spain. First of all, they have advanced football concepts, and secondly they have a productive youth training system, which we can learn
