Hi, thanks for the help but "Kajaran" and Karapet Mikaelyan are definitely two different players.
Karapet Mikaelyan made 15 appearances for Yukong in 1997, but this mystery player in question made the two appearances in 1992 (for the record, the dates of his appearances were April 4th and June 13th).
I did wonder if the player in question could be either Ashot Khachatryan or Vardan Khachatryan - the date of births are both incorrect but then I've spotted similar mistakes in the K-League records with other foreign players too.
According to the Player History website, Ashot played for Ararat Yerevan in the Soviet Union from 1976~1991, but there is no information on his career after that date. He did, however, play for the Armenian national team in 1994 so I would imagine he continued playing somewhere, which may have included Korea.
Vardan's birthdate is October 29th 1968 which shares some similarities to the mystery player (October 28th, 1961), so could just be a simple case of entering the wrong details in the archive. He played 27 times for Ararat in 1992 though so seems unlikely he spent a minimum of two and a half months of that year in Korea.
As FCArarat pointed out, it could be any number of spellings... bah.
Thanks for the help so far, everyone
