Yang has been quoted in the South Korean media as saying that he wants to sign for Celtic this summer but his club, Gangwon, would rather wait until the end of their season, which finishes in October.

Gangwon sits 11th in the 12-team K-League 1 and would face a relegation play-off if it remains there.

The player’s representatives earlier claimed Yang had been promised he would get the chance to move if a European club came in for him and was frustrated at the club’s stance.

Celtic has achieved success over the past two seasons by recruiting in Asia, with Kyogo Furuhashi named PFA Scotland and Scottish Football Writers’ player of the year last term.

The striker was joined by several Japanese colleagues including Daizen Maeda, Reo Hatate and Tomoki Iwata after Postecoglou arrived from Yokahama F Marinos two years ago. Celtic also signed South Korea striker Oh Hyeon-gyu in January.

New manager Brendan Rodgers is keen to continue the successful recruitment tactic along with the club’s head of scouting and recruitment, Mark Lawwell.

Quoted in several newspapers, Rodgers said: “Over the course of our discussions I’ve seen the market we’re in and how well the recruitment has gone.

“Mark Lawwell has this pipeline of players that are available and I think what he’s done since he’s come in has been really impressive – and the markets he’s been able to tap into. That will continue. That’s where the club is at.

“In terms of recruitment I am the one that knows how I want the team to play and I have to be involved in those discussions. And I will be. Some of those markets haven’t been as readily available to some clubs, that’s something Mark has brought with him in his roles.

“I’m thinking of the Japanese market, the Korean market, Australia and out into Asia. These were players that were untapped and you’re now seeing other clubs trying to tap into that.”
