Beijing Guoan leads the Chinese Super League clean sheet race with 10 after 27 rounds, but Chongqing Tonglianglong, Dalian Yingbo, Tianjin Jinmen Tiger, Qingdao West Coast, and Chengdu Rongcheng sit within one or two of that mark, each conceding roughly 1.15–1.22 goals per game. This parity stems from comparable defensive organization across the group, where strong home records and disciplined backlines have produced similar shutout totals despite varying league positions and goal differences. With three rounds remaining, minor swings in form, set-piece vulnerability, or goalkeeper rotations could easily reorder the standings, keeping implied probabilities clustered tightly as traders weigh the narrow margins.
