SEOUL, South Korea — Takashi Usami scored twice in the second half Wednesday as Gamba Osaka beat FC Seoul 3-1 to take a two-goal advantage into next week's return leg in the round of 16 of the Asian Champions League.
Usami, who leads the J-League with 10 goals, volleyed home in the 62nd minute and Koki Yonekura doubled the advantage 11 minutes later to put the 2008 champions in control.
Usami added another in the 86th before Yun Ju-tae pulled one back for the hosts in stoppage time.
The Japanese side lost its first two games of the group stage but qualified for the last 16 after topping Group F with 10 points from next four matches.
In Seongnam, captain Kim Do-heon scored a 96th minute penalty as two-time Asian champion Seongnam FC edged 2013 champion Guangzhou Evergrande 2-1.
Huang Bowen netted an equalizer for the visitors three minutes before halftime after Jorginho opened the scoring for Seongnam midway through the first half.
In west Asian matches Wednesday, Al Ahli and Al Ain played to a scoreless draw in a United Arab Emirates' derby, and Naft Tehran won its home leg against Al-Ahli of Saudi Arabia 1-0.
In Tehran, Gholamreza Rezaei scored the only goal of the game with 11 minutes remaining in the first half to give Naft the edge going into the second leg in Jeddah next week.
Naft coach Alireza Mansourian, a former Iran international midfielder, said his team's level of play dropped after the goal.
"I'm happy with the result, but not my player's performance in the second half," Mansourian said.
Al Ain coach Zlatko Dalic said he was expecting a difficult home leg next week when his side takes on Al Ahli for a place in the quarterfinals.
Ibrahim Daiky, Asamoah Gyan and Jires Kembo-Ekoko all had chances to give Al Ain a valuable away goal advantage at Al Ahli's Al Rashid Stadium in Dubai.
"The match was very hard for the two sides and the cautious approach affected the performance of the two teams," Dalic said.
