Hi, in the match South Korea vs Poland (2:2) played 2011-10-07 (https://www.national-football-…2/South_Korea_Poland.html) Hong, Chul didn't play for South Korea.
Here (http://www.kfa.or.kr/archive/p…ch_val=%ED%99%8D%EC%B2%A0) you can see the matches played by him with the national team in the official website of KFA (this match doesn't appear) and here (http://www.kfa.or.kr/national/…rsor=#cursor_location_sub) you can see the report (maybe confused with Hong, Cheol),
Hi - which Hong Cheol would that be? Because in all the sources I could find (had a brief look) it seems that Hong Chul actually did play. That match against Poland was unofficial, though. The link you posted will not open for me.
