SHANGHAI (Interstat) — Shanghai Haigang FC and South Korea’s Ulsan played to a scoreless draw in their AFC Champions League group stage opener Wednesday at SAIC Motor Pudong Arena.

The match, which defied a pregame projection favoring Ulsan with a 62.3% win probability, saw few clear chances. Defensive discipline defined the contest, with Shanghai’s Yang Alex and Ulsan substitute Cho Hyuntaek each receiving yellow cards in a physical second half.

The result leaves both clubs with identical records in the competition and across all competitions this season: 0 wins, 0 losses and 1 draw. The stalemate fell short of the Interstat game simulator’s projected 1-1 final score.
