Urawa Reds ended Shanghai SIPG's perfect record in the Asian Champions League and took the Group F lead with a 1-0 victory on Tuesday after Oscar missed two penalties in the second half.
Rafael Silva scored the lone goal late in the first half at Saitama Stadium, where Urawa moved level with SIPG on nine points after four games but grabbed the top spot on head-to-head.
"I've had a lot to think about this season from an individual standpoint so I went into the game trying to stay strong," Urawa goalkeeper Shusaku Nishikawa said. "They really pushed us in the second half but our fans really bailed us out with their support.
