The Millionaires have already made two high-profile signings this summer, having splashed the cash on striker Pierre-Emerick Aubameyang and midfielder Henrikh Mkhitaryan, but, at the same time, they are also thinking about the future.
Bild has suggested that Korean hotshot Ryo Seung-Woo is set to become a Borussia Dortmund player in the coming days.
Namely, the Millionaires are close to agreeing a €400,000 fee for the talented footballer, who is expected to sign a three-year contract at Signal-Iduna Park.
The 19-year-old arrives from Chung-Ang University and will probably spend some time in the reserves before being promoted to the first team set up.
Ryo Seung-Woo shone at the Under-20 World Cup in Turkey, scoring two goals in three appearances for South Korea, including a screamer in group stage against Portugal.
