Concerned Yang Hyun-jun has warned Gangwon that Celtic won't "wait forever" as he attempts to force through a move to Celtic Park.
The 21-year-old has been locked in a battle with his club with the K-League outfit unwilling to allow the winger to leave mid-season while they are battling to avoid relegation this term, despite promises to Hyun-jun that he could leave for Europe when an offer came in after a move to Major League Soccer side Minnesota United was blocked last year.
The position of Gangwon appears to have softened with the club stating they will "review" talks with the Scottish Premiership champions. Record Sport understand a £2.1million deal is edging closer but Gangwon reportedly hope to secure a replacement before allowing the key man to make a dream move to European football.
Chosun report that a deal is being delayed while the Korean outfit await the arrival of Welinton Junior from Portuguese side Portimonense this summer.
