Only Pierre-Emerick Aubameyang - now at Arsenal - has ever had a longer run for the club, with 11 home goals in a row.

Sancho tapped home Thorgan Hazard's cross from six yards out for the game's only goal.

The 19-year-old winger has now scored 14 goals and assisted another 14 in the league this season.

Dortmund remain third, four points behind leaders Bayern Munich.

In-form Erling Braut Haaland came on in the 63rd minute and failed to score in a home league match for the first time since September 2018 when his Molde side lost to Rosenborg in Norway's top flight.
