In recent years, the Chinese football league system has undergone significant changes, with the introduction of new rules and regulations that have brought about some notable developments in the game.
One such change is the implementation of the "wing defender" concept, which was introduced by Guoan FC during the 2017 season. This move allowed the club to use a more disciplined and focused approach to their attacking play, while also providing greater protection for their players.
Under the wing defender model, Guoan FC's midfielders would be given a more concentrated role, with a focus on defending against crossbar attacks rather than trying to break through the defense themselves. They would also be expected to maintain possession and defend deep into their opponents' half, using their height and strength to limit their space and prevent the opposition from getting behind them.
The results of this move have been mixed, as Guoan FC struggled to establish a strong defensive line early on, particularly in the first few games of the season. However, they have since improved significantly under the wing defender philosophy, and now boast one of the strongest defenses in China's top flight.
In addition to improving their defense, the wing defender model has also helped Guoan FC to develop their young talent. With players like Cheng Shengyu and Zhao Huan playing at the highest level, Guoan FC has seen a renewed sense of confidence and ambition in their attack.
Overall, the wing defender model is a positive development for Guoan FC, as it provides them with a disciplined and focused approach to their attacking play, while also giving them greater protection for their players. As they continue to improve under this new philosophy, it will be interesting to see how the club fares in the upcoming season.
