The Turkish defender has already agreed a deal to move to Thomas Tuchel’s side, according to various media sources in Germany
Borussia Dortmund will sign defender Omer Toprak from Bayer Leverkusen in the summer, according to Bild.
A €12 million transfer fee has been agreed between the two Bundesliga sides, with the Turkish centre-back set to sign a four-year contract with BVB.
The 27-year-old has been with Leverkusen since 2011, when he moved from Freiburg.
Toprak is seen as an ideal purchase by Thomas Tuchel, especially after Mats Hummels left Dortmund for Bayern Munich and replacement Marc Bartra’s poor performances of late.
