The 19-year-old — who joined the German club from Red Bull Salzburg last month — has now scored seven goals in his first three matches.
He doubled his side’s lead in the 18th minute after Jadon Sancho had opened the scoring, and the Norwegian striker put the icing on the cake with a low drilled effort for the fifth goal of the game.
Marco Reus and Axel Witsel scored the other goals of the match.
Håland has now played a combined 136 minutes for Dortmund, and is averaging a goal roughly every 19 minutes.
He is also now the first player in Bundesliga history to score seven goals in their first three games.
His promise had attracted plenty of attention from Europe’s top clubs, especially after he scored 22 goals in 18 appearances for Salzburg, including four hat-tricks in the Austrian top flight and the Champions League.
However, Dortmund won the race for his signature in January and the signing is certainly paying off.
The German club is now third in the Bundesliga on 39 points, three points behind rivals Bayern Munich at the top of the table.
