Osaka earned a thumping 5-0 victory over the Chinese side with Lam rarely troubled by the opposition.
Osaka head coach Levir Culpi played Lam in this match after putting him on the bench in previous games, and the 28-year-old keeper had a pretty easy game. He only had to block a single shot and had four touches.
In the first half, Osaka dominated with 68.2 percent possession, 13 shots and one goal, while Guangzhou only managed one shot off target. Lam’s only save in the game came in the 50th minute when he stepped out of the goal to clear a dangerous pass.
Three minutes later, Osaka doubled their lead and found the net again in the 66th and 72nd minute, before wrapping things up with another goal in the last minute.
Osaka’s victory kept them on top of group J with 14 points after five games and took the team to the next round.
In June, Lam played his very first game for Osaka in a Emperor Cup match against Gainare Tottori. He also kept a clean sheet then.
Vietnam’s goalkeeping ace is still awaiting his debut in Japan’s top division J1 League.
Before playing in Japan, Lam had joined Thai club Muangthong United in 2019. He had 42 appearances for the club over two seasons. Earlier this year, he agreed to join Osaka and officially signed for the club in April.
