Ji So-yun has signed a two-year contract with the Chelsea Ladies in England's Women's Super League, the club announced on its website on Monday.
"She is one of the best midfielders in the world and our fans will love her," said the team's manager Emma Hayes, who has had her eyes on the player for the last two years. "She has got everything and is a great fit for our team, and I've no doubt she will prove a big success in a Chelsea shirt."
Ji, who became the first Korean to play in the WSL, said, "I am glad to be joining Chelsea Ladies and look forward to the new challenge of playing football in Europe."
The WSL, run by the British Football Association, was founded in April 2011. The league kicks off in April and runs until summer so it does not overlap with the English Premier League.
Ji will depart for London on Tuesday afternoon.
