The Japan Under-18 international will make the move to the Signal Iduna Park this winter as he aims to emulate Shinji Kagawa.

Borussia Dortmund have announced the signing of promising midfielder Mitsuru Maruoka from Cerezo Osaka on an 18-month loan deal.

The 17-year-old will join the Bundesliga giants on January 6, when he turns 18, and will start his European career in the club's Under-23 side, playing in the 3. Liga.

Dortmund have the option to make Maruoka's stay at the Signal Iduna Park permanent at the end of his one-and-a-half-season loan spell.
