The hosts made the perfect start in chilly conditions when midfielder Park moved to the near angle of the six yard box to flick Kwon Chang-hoon’s corner towards goal with a header that looped beyond Sumethee Khokpho’s dive to the right.

Tiago Orobo had the opportunity to add a second for the hosts 13 minutes later but his header was too weak to trouble Sumethee, who gathered with ease.

Port almost found a way through at the other end with 20 minutes on the clock. Felipe’s corner from the left was met by Jeonbuk goal scorer Park, the ball flying across the face of goal to give the home defence a fright.

Pakorn Parmpak then let fly from 20 yards as the half drew to a close, but the shot was too close to Kim Jeong-hoon and the Jeonbuk goalkeeper easily collected.

Felipe Amorim’s weakly struck effort nine minutes into the second half did little to trouble Kim and at the other end Tiago squandered the opportunity to double his side’s lead, putting his shot too close to the goalkeeper and Sumethee cleared with his foot.

Kang Sang-yoon flashed a right-foot over the bar when he took aim for the top corner of Sumethee’s goal while Asnawi Mangkualam thumped wildly over the bar in the dying minutes in a rare sight of goal for Port FC.

Anon Amornlertsak’s looping effort bounced on top of the Jeonbuk crossbar as the game inched into injury time as the Thai side’s hopes of a consolation were thwarted.
