Hosts Qatar is set to take on South Korea for a place in the final of this year's AFC Under-23 Championship and berth at the Rio Olympics.
"We are in the last part of the competition - every game is going to be harder and harder because the opposition is of the very highest quality and pressure is the same as all others games because each game (is) like a final for us. And in the same time we are proud to be at this stage of the competition. So we feel more than pressure - we feel proud to be here and to make a last effort to reach (the next) stage," says Qatar coach Felix Sanchez.
The other semi-final match tonight will see Iraq up against Japan.
