Seongnam FC and Guangzhou R&F played out a goalless draw in their AFC Champions League match on Tuesday.
Supporters at the Tancheon Sports Complex outside Seoul had very little to shout about in the first half of the match in which the respective goalmouths were seldom threatened.
While the match remained a cagey affair after the interval, there were a few more goal-scoring chances, albeit mostly through hopeful shots from range.
Ten minutes after the half-time break Kim Do-heon made sweet connection his shot on the half-volley but he was unable to trouble Guangzhou goalkeeper Liu Dianzuo.
Hwang Ui-jo thought he broke the deadlock in the 70th minute when he broke the Guangzhou off-side trap and managed to calmly roll it past Lin, but he was correctly flagged for offside by the referee's assistant.
Seongnam continued to press for the first goal of the match and with 15 minutes remaining substitute Kim Dong-sub had a fierce shot well saved by Liu, before the keeper gathered calmly from a Lucas shot soon after.
Guangzhou struggled to create many scoring opportunities from open play but looked threatening from set pieces and had their best chance of the match with eight minutes remaining as Park Jong-woo found Abderrazzaq Hamedallah unmarked in the box, but the Moroccan striker's tame shot was easily saved by goalkeeper Park.
The Chinese side was nearly made to pay for their profligacy with two minutes remaining on the clock when Kim Cheol-ho's measured cross found Hwang Ui-jo, but the striker's header went well wide of the mark.
The result leaves the Korean side on top of the standings in Group F on seven points ahead of Buriram on goal difference.
Guangzhou are three points behind in third place alongside Gambia Osaka.
