Adnan Januzaj scored on his debut for Borussia Dortmund as the Bundesliga club earned a 2-1 victory over St Pauli in a friendly in Hamburg.

Dortmund opened the scoring in the seventh minute when Gonzalo Castro drove to the edge of the box and fired a low strike into the bottom corner.

Januzaj then doubled their lead 11 minutes later with a deflected effort that flew past the stranded goalkeeper.

Fafa Picault pulled a goal back for the second division side with a close-range header, but they were unable to trouble the scoresheet again as Dortmund claimed the win.

The match was being played to help raise awareness of the ongoing refugee crisis in Europe.
