The 27-year-old made his professional debut with Jeonbuk in the 2018 AFC Champions League™ against Kitchee and was part of the squad that won the K League title in 2018, 2019, 2020 and 2021.

Song was also a member of the Korea Republic squad that claimed the gold medal at the Asian Games in 2018 and was in goal when the country lifted the AFC U23 Asian Cup™ two years later.

He returns to a Jeonbuk side that no longer dominates the K League, with the club only narrowly avoiding relegation last season.

Jeonbuk have, however, advanced to the last 16 of the AFC Champions League Two™ 2023/24 and will face Port FC from Thailand in the knockout rounds when the competition resumes in February.

Poyet’s team will go into that competition without experienced Korea Republic international fullback Kim, who has brought an end to his second spell with Jeonbuk.

The 32-year-old left back, a five-times winner of the K League title during his time with Jeonbuk, has previously played in Japan, Germany and Saudi Arabia.

Meanwhile, Ulsan HD have confirmed the departure of Japanese midfielder Ataru Esaka.

Esaka, an AFC Champions League™ winner with Urawa Red Diamonds in 2022, leaves the K League side after two seasons, where he won back-to-back domestic titles and helped the club to the semi-finals of the AFC Champions League ™ 2023/24

The 32-year-old midfielder has signed with newly promoted J1 outfit Fagiano Okayama.
