The teenager continues to catch the eye, having consolidated his place in Dortmund's side this season, starting every Bundesliga and Champions League game so far.
According to Bild, the German side have valued Bellingham at £101m in an attempt to warn off any potential suitors.
The 18-year-old's current contract in Germany lasts until 2025 and this news increases the chances of him staying for the entirety of that deal.
Since making the switch from Birmingham City last year, Bellingham has made 61 appearances for Dortmund and scored seven goals. body check tags ::
