North Korean An seeking move from South
The Japanese-born midfielder moved from J-League side Nagoya Grampus to South Korea with Busan in 2006, moving on to Suwon two years later.
"We have decided not to re-sign with Suwon Bluewings," the 31-year-old's agent told the Korea Times newspaper.
"Currently, J-League and European league teams are interested in him and we are in negotiations."
Even though his parents were also born and raised in Japan, An holds only a North Korean passport and is one of only three overseas-based players likely to make the squad for South Africa.
