Nekounam and Osasuna made it to the final of UEFA cup, so youre both wrong. Nakamura and Nekounam BOTH had outstanding performances on European stage and deserve this award, but AFC will just give the award to Al-Qahtani or Mahmoud.
Actually Osasuna made it to the semi finals, where they lost to Sevilla in the second match (2-0) after they had already won against them at home (1-0). I was talking about his goal against Bordeaux in the last seconds of the extra time (minute 120), he took his team to the quarter finals with that goal. He didn't play in the quarter finals against Bayer Leverkusen because he was injured for a few weeks.
Read the link it says the South Korean Association Banned the player, any way do you really think Lee Woon-Jae has a chance to win it?
