Chelsea and Manchester United are keeping tabs on Borussia Dortmund goalkeeper Gregor Kobel.

Blick says Kobel's form this season has brought him to the attention of Europe's biggest clubs.

Chelsea see Kobel as a potential replacement for Edouard Mendy, while United are preparing to sell Dean Henderson and have identified Kobel as a potential successor. He would arrive as cover for David de Gea.

Dortmund is in no hurry to sell Kobel, whose contract does not expire until the summer of 2026.

He joined Dortmund in the summer of 2021 when he was bought from Stuttgart.
