Dortmund won their fourth game in a row, and their third 1-0 victory of the season.
Reus opened the scoring after 16 minutes, slamming in a pass slid in by English teenager Jamie Bynoe-Gittens following some inventive work from the outstanding Julian Brandt.
The Ruhr valley team hosts Copenhagen in their Champions League group opener on Tuesday.
Reus’ goal was his 146th in 345 Bundesliga games, and the 60th time he put his club up 1-0.
Dortmund leads the table with 12 points, two more than second-placed Bayern Munich. Hoffenheim is fifth with nine points.
Dortmund failed to add another goal in a dominant first half and had to overcome a shaky second half start with Hoffenheim playing with greater energy and committing more men forward.
In the 67th minute, Hoffenheim goalkeeper Oliver Baumann made a double save, first stopping substitute Thorgan Hazard’s strike and then blocking Anthony Modeste’s rebound chance.
Dortmund suffered a setback when teenager Jamie Bynoe-Gittens dislocated his shoulder just before halftime.
“It was an unfortunate incident that did not appear to be dangerous at the time, but the shoulder popped out.” “We hope he returns soon,” Terzic remarked.
Dortmund are already without midfielder Mo Dahoud, who will be out for months after undergoing surgery for a shoulder injury.
Marco Reus prefers watching Premier League over Bundesliga
Marco Reus reveals that he prefers watching the Premier League or La Liga than other leagues.
The 33-year-old forward, who has made over 300 Bundesliga appearances for his boyhood club Borussia Dortmund, is well-versed in the German division.
In addition to his ten years at the Westfalenstadion with his beloved Dortmund, which he now captained, Reus spent three years with Borussia Monchengladbach between 2009 and 2012.
Reus has already rejected down lucrative offers to stay with ‘BVB’ in the Bundesliga.
However, in a recent interview with The OMR Podcast, the seasoned forward revealed that he prefers to watch other leagues rather than Germany’s top flight.
During the refreshingly honest chat, Reus opened up about a number of topics, but also spoke about watching other leagues in his spare time.
“Honestly, I prefer to watch the Premier League or La Liga,” he said. “Like when Barca plays against Real [Madrid]. I know a little bit about the Premier League. It’s a special game when City plays United.”
Reus also spoke about Borussia Dortmund’s current situation when it comes to transfers.
“It’s always a shame to see that we sign incredibly good young players who then unfortunately have the dream of developing somewhere else after two or three years,” Reus told The OMR Podcast.
