Ulsan Hyundai got their first win of the Asian Champions League when they defeated Beijing Guoan 1-0 at the Ulsan Muntu Stadium.
Substitute Oh Jang-eun used his predatory instincts to net the game's only goal in the 69th minute after a shot deflected back off the crossbar.
The Korea international was able to finally beat Beijing keeper Yang Zhi and give Ulsan a crucial win that has kept their hopes alive in the tournament.
Beijing will be kicking themselves for the loss as a win or draw would have seen them sitting pretty on top of the Group E table.
