Transfer negotiations are ongoing between Stuttgart and Hoffenheim over Grischa Promel, the highly-rated midfielder - with multiple reliable sources confirming the story. The clubs are believed to be some way apart on valuation, but dialogue is open as they look to strike a deal ahead of the run-in. Unconfirmed reports suggest both sides are hopeful of finding a resolution in the coming days - with other interested clubs said to be circling. Negotiations are still active, and with no other teams linked, Stuttgart appear to have a clear path to completing the deal. So far this season, Stuttgart are steady at both ends (1.88 goals scored per game, 1.47 goals conceded per game). The role for Grischa Promel would be to keep that balance while lifting performances across the pitch. Speculation continues to connect Hoffenheim with Mirza Catovic and William Cole Campbell while no fresh rumours surround Stuttgart. Stay tuned for more details as the story develops.
