Muangthong United secured a valuable 1-0 victory over Ulsan Hyundai at SCG Stadium.
The win means the Thai club moved to the top of Group E with eight points after two wins from four games.
Teerasil Dangda was the hero of the night for the hosts, scoring eight minutes before half-time to bring home the victory.
Ulsan had most of the possession but failed to turn any of it into clear-cut chances, with the only two shots on target being easily dealt with by Muangthong stopper Kawin Thamsatchanan.
The other Group E clash saw Brisbane Roar gain their first three points in their 2017 AFC Champions League campaign after edging Kashima Antlers 2-1.
Forward Jamie McLaren would score the first goal in the 18th minute before Brett Holman doubled the hosts’ lead in the 49th minute.
Substitute Ryota Nagaki gave Kashima some hope when he scored from close range 11 minutes before time, but it was too little too late.
Kashima Antlers remain in second with 6 points, two points behind leader Muangthong. Brisbane are still bottom but now have 4 points, same as third place Ulsan Hyundai.
Meanwhile, Suwon Bluewings consolidated their top spot in Group G with a thumping 5-0 victory against Hong Kong’s Eastern.
Yeom Ki-hun headed home the opener in the 37th minute, befoe Ko Seung-Beom added the second 15 minutes into the second-half.
Johnathan bagged a quick-fire brace and Seung-Beom sealed the victory for the host with his second of the night just several minutes later.
Suwon are still undefeated after 4 matches and held on to their top spot, while Eastern’s campaign seems all but over with just a single point and a goal difference of -13.
Second-place Guangzhou Evergrande and third-place Kawasaki Frontale held each other to a draw last night at Kawasaki Todoroki Stadium.
Both sides had their chances but couldn’t turn them into anything substantial and a draw was probably a fair result.
