Henan's defense has seen significant improvement this season, with tactical analysis indicating that a series of adjustments on the backline is effectively enhancing the team's defensive efficiency.

Firstly, the introduction of Iago Maidana and O. Gerbig has strengthened the stability of the defense, particularly excelling in set-piece situations. In confrontations with opponents, their physical presence has posed considerable challenges for adversaries.

In addition, Henan's current defensive system employs a four-back formation to increase lateral movement speed. This allows the team to transition from defense to attack more rapidly and effectively. Moreover, goalkeeper Wang Guoming's leadership greatly enhances the cohesion of the backline.

This defensive strategy has enabled Henan to frequently achieve clean sheets against strong teams. Whether the team can continue to maintain this robust form depends on how they cope with different styles of opponents in upcoming matches.
