Ghanaian midfielder Joachim Aduko will wear the No.18 shirt for SK Sarajevo.
The 27-year-old completed his transfer to the Bosnian outfit after ending his stay with Diósgyőri VTK.
He made only seven appearances in the Hungarian elite division last season.
The club is confident the Ghanaian still has the quality and is hoping he will give them a squad boost in the 2020/2021 football season.
Adukor has gathered experience over the last few years after playing for clubs including Gefle IF, OFI Crete, CD Trofense, and AS Béziers.
