Beijing Guoan coach Lee Jang-soo is looking for a much-improved display in tonight's Asian Champions League clash against Ulsan Hyundai.

The Chinese club went down to the Korean outfit when the sides last met a fortnight ago and will be out to avenge that loss and push themselves towards progressing to the round of 16.

"In our last game played away against Ulsan we played badly, you could say even shamefully," said Lee.

"This time we are back on our own pitch and we must try our best to play much better.

"Tomorrow's game will be key to our qualification from the group stage."
