Transfer negotiations are ongoing between Frankfurt and Newcastle over William Osula, the highly-rated forward - 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. While Frankfurt and Newcastle continue talks, no breakthrough has been reported. Ajax and Aston Villa reportedly may still have an interest, but currently the focus is on getting this deal across the line. At 2.83 goals scored per game this season, Frankfurt already pose a big threat. William Osula would be expected to maintain that level and give them another reliable option in attack. Reports suggest Newcastle are monitoring Teun Koopmeiners, Guler Arda and Marc-Andre ter Stegen whereas Frankfurt have not been associated with other players at this stage.
