Reigning Asian champions Gamba Osaka remain undefeated in this seasonâ€™s competition.
The Japanese outfit accounted for Indonesian club Sriwijaya 3-0 overnight to go three points clear on top of the Group F table.
Gambaâ€™s Leandro opened the account at the Jaka Baring Stadium with a strike in the 30th minute before Hayato Sasaki doubled the advantage just prior to half-time.
The visitors dominated much of the proceedings in the second half but could only add one goal, in the 75th minute through Cho Jae-jin.
Gamba coach Akira Nishino said he was proud of his side for producing a quality performance and was looking at the ultimate prize once again.
â€śSriwijaya have proven that they are not easy to beat at home, regardless of the score line,â€ť said Nishino.
â€śThey made some chances and were threatening for a while but once we solved their offside trap and scored the opener, everything became easier for us.
â€śObviously we have the same target as last year - to become champions again,â€ť added the Gamba boss.
