Celtic sign South Korean midfielder Kwon Hyeok-kyu from Busan I'Park

The 22-year-old moves to Parkhead for a fee believed to be in the region of £1m and has penned a five-year contract until 2028.

Kwon is the second South Korean to join Celtic on Monday following the arrival of attacker Yang Hyun-jun from Gangwon for around £2m.

Yang and Kwon have become Brendan Rodgers's third and fourth signings of the summer transfer window after attacker Marco Tilio and midfielder Odin Thiago Holm.

"This is a great move for me, to be joining the Scottish champions, and I am looking forward to working with the manager and the players," Kwon told Celtic's official website.

"I know that Celtic is already very well-known back home, and I am sure the support will continue to increase now there are three South Korean players, and it will be good to play alongside them."

Rodgers added: "We're also very pleased to bring Kwon to the club, on the same day that we've also announced the signing of Yang.

"Again, he is a player that the club has been aware of for some time, so it's great that we've completed the deal and I know that the player is delighted with the move.

"We're looking forward to both players joining up with the squad and playing their part in what we hope will be another successful campaign."

Kwon, primarily a defensive midfielder, departs Busan I'Park after making 44 first-team appearances for the South Korean second-tier club, scoring three goals.

The 11-cap South Korean Under-23s international could make his competitive debut for Celtic in their opening Scottish Premiership match of the new season at home against Ross County on August 5.
