The Japan international will join on a loan until the end of the season for a €1.1m fee and will replace Tolgay Arslan who joined Fenerbahce yesterday.

Besiktas have made strengthening the midfield a priority over the winter transfer window but the Kagawa deal also has a commercial angle.

The Istanbul based outfit have been targeting the Japanese market and recently signed a sponsorship deal with the newspaper group Mainichi.

Additionally, the Besiktas basketball team is also sponsored by the Japan Sompo insurance company.

The Black Eagles have a growing interest in the region and hope the latest transfer will help develop relations further.

Kagawa joins Burak Yilmaz, Nicolas Isimat-Mirin and Muhayer Oktay as the fourth January transfer.

The 29-year-old struggled for playing time at Dortmund this season making just five appearances in all competitions.
