Wang Gang is one of China's most successful coaches, having led his team, Guoan, to their first ever Chinese Super League win in 2017.

In February 2017, Wang Gang was appointed as the new head coach of Guoan, replacing previous coach Li Junwei. Prior to that, Wang Gang had been working for Guangzhou Evergrande since 2015, and he had previously served as the head coach of the Hong Kong Premier League side, New Zealand Warriors.

Since taking over, Wang Gang has implemented several strategies that have helped Guoan to become a force to be reckoned with in Chinese football. He has emphasized on developing young talent, which has paid off handsomely for Guoan, who has produced several promising young players like Xie Wenbo, Wang Zhengyi, and Lin Shuhao.

The success of Guoan under Wang Gang's leadership has also brought about significant improvements in the club's financial situation. The club has seen a marked increase in revenue from sponsorships, ticket sales, and other sources, and this has helped to improve the overall image of the club.

However, there has been criticism of Wang Gang's approach towards the development of young talent. Some fans and supporters have criticized him for not giving enough time to develop young players, while others have accused him of being too focused on winning trophies rather than nurturing the next generation of talent.

Despite these criticisms, it remains unclear whether Wang Gang will continue in his current role or if he will seek to make changes in his coaching style in order to improve the club's performance. Time will tell, but it is clear that Wang Gang has made a positive impact on Guoan and its young players, and it remains to be seen how he will continue to lead the team in the future.
