Borussia Dortmund hierarchy are preparing to open formal contract negotiations with first-choice goalkeeper Gregor Kobel in the coming weeks, seeking to ward off concrete interest from French champions Paris Saint-Germain.

According to a report from Sport Bild, the Bundesliga outfit is eager to wrap up an improved extension before the winter break, effectively superseding his current terms, which run through to 2028. While the 28-year-old Switzerland international is open to extending his stay at the Signal Iduna Park, discussions are expected to prove demanding given the escalating competition for his signature among Europe's elite.

PSG have emerged as the leading suitors for the Swiss shot-stopper, with Parisian emissaries regularly inquiring about Kobel’s long-term plans as they explore options to reinforce their goalkeeping department.

The French giants are not the first heavyweight to test Dortmund's resolve. Newcastle United previously launched a lucrative approach, offering Kobel an estimated annual salary of around €13 million—a roughly €3 million increase on his current earnings in Germany. That transfer collapsed after the goalkeeper himself rejected the switch, unconvinced by the competitive scope of the Magpies' sporting project.

Now, Dortmund's board must not only present an attractive financial package to their undisputed number one, but also demonstrate that the club's on-pitch ambitions match his own in order to fend off renewed advances from continental powerhouses.
