Ulsan Hyundai coach Kim Ho-gon believes the clash with Beijing Guoan is their most important in the Asian Champions League.

The Korean club is currently sitting on the bottom of the Group E table with three points from three matches and will need at least a point tonight to stay in the hunt.

"Tomorrow's match is our most important match because up until now in the group stages we have already lost twice and got only one win," said Kim.

"We are preparing for this match as our most important because we want to qualify for the next stage.

"We have to win this game if we want to qualify."
