Pohang Steelers inflicted a first Asian Champions League defeat on treble-chasing Vissel Kobe 3-1 on Tuesday, as Yokohama F. Marinos and Gwangju took another step toward the knockout round.

Kobe racked up four wins and one draw from their opening five games but Vissel could not cope with a hungry Pohang side looking to haul itself into the eight qualification places in the east table.

Han Chan-hee and Kim In-sung gave the South Korean side an early two-goal lead before Kobe's Daiju Sasaki pulled one back from the penalty spot before halftime.
