Eintracht Frankfurt have signed 20-year-old Japanese midfielder Daichi Kamada from Sagan Tosu on a four-year contract.
Kamada has scored three goals and set up a further two in 16 matches in Japan in the current J-League season, and DFB Pokal finalists Frankfurt are reported to have paid €2.5 million for him.
"Daichi has a lot of potential. We've seen him play many times," Frankfurt sporting director Fredi Bobic told the club's official website.
"He makes our attacking midfield more variable."
