FTBL understands Davidson is to depart the Glory and sign for Ulsan immediately.

Sources in Korea indicate the K League 1 club has paid a transfer fee to land the left back on a multi-year deal.

Davidson was one of Perth's most consistent performers last season as they claimed the Premiers Plate and reached the A-League grand final.

The Socceroo made 28 appearances in the 2018/2019 campaign, missing just one game, scoring two goals and notching five assists.

The 27-year-old signed for Glory from Croatian club Rijecka in August last year.

Davidson has had one stint in Asia before, spending three years as teenager in Japan developing his game with Seiritsu Gakuen.

The defender has played around the world during his 11-year professional career with spells in Portugal, Holland, England, Croatia and Slovenia.

Davidson, the son of Socceroo great Alan, has 22 caps for the national team.

Ulsan Hyundai are one of the biggest clubs in Korea and won the Asian Champions League in 2012.

In 2019 they are currently in second top in the K League 1 behind Jeonbuk Hyundai Motors.
