Chunnam Dragons striker Ji Dong-Won is mulling over offers from Sunderland and PSV Eindhoven.
Ji, who spent time training with Championship side Reading during his youth career, says he wants to go where he will be guaranteed first-team opportunities.
"My team and agent are still negotiating closely (with two teams)," Ji told Yonhap News.
"Personally, I want to play at the best possible team where I have the best chance of playing time.
"PSV is a great club that often finishes at the top of the league. But I've heard the level of the Dutch league is no longer what it once was.
"Sunderland is a team whose squad is always changing because it is a mid-level club. But they are playing in the Premier League."
