Celtic have confirmed the signing of 21-year-old South Korean winger Yang Hyun-jun.

The attacking player has moved from Gangwon on a five-year contract to link up with compatriot Oh Hyeon-gyu and become Celtic’s third summer signing.

Manager Brendan Rodgers told Celtic’s website: “We’re delighted to bring Yang to the club and I’m sure he’s going to be another great addition to the squad.

“He’s a player that we’ve looked at closely and who we think will further enhance our attacking options which, of course, already include his fellow countryman Oh.

“He’s an exciting player who was the young player of the year in South Korea last season, which is an indication of his quality, and I’m sure he’ll be looking forward to having a big impact at the club.

“It’s also clear that he was very keen to make this move to Celtic so I know he’ll be delighted that everything has now been agreed and we’re really looking forward to working with him.”

Yang’s club had been hoping to keep him until the end of their season but the player made it clear he wanted an immediate transfer rather than waiting until the January transfer window.

He said: “I’m very pleased to come to Celtic and I’m looking forward to meeting my new team-mates and to begin training with them.

“This is a move that I wanted to make and so it is great to be here in Scotland now as a Celtic player.

“I have spoken to Hyeon-gyu Oh who has already told me great things about the club and its supporters, so I can’t wait to meet them and play in front of them.”
