Chelsea Ladies sign South Korean midfielder Ji So-Yun

Chelsea Ladies have signed South Korea international Ji So-Yun.

The 22-year-old, who has scored 26 goals in 55 appearances for her country after making her debut at 15, has agreed a two-year deal.

"She is one of the best midfielders in the world and our fans will love her," said Chelsea manager Emma Hayes.

Ji, a three-time Korean footballer of the year, is the club's fifth signing ahead of the new Women's Super League season, which starts in April.

Chelsea have already recruited England quartet Rachel Williams, Laura Bassett, Gilly Flaherty and Katie Chapman.
