The 29-year-old was given the skipper's armband over the summer by new coach Lucien Favre, who was effusive in his praise of the winger: "Marco's a role model, has lots of experience and has been at the club a long time. He's the logical choice."
Equally logical for Reus is the need to get Dortmund challenging for silverware again following a disappointing 2017/18 campaign in which they finished fourth in the Bundesliga, were knocked out of the DFB Cup in the Round of 16 and failed to progress beyond the group stage in the UEFA Champions League.

Indeed, such is his desire to drive BVB back to the top that he penned a long-term contract extension in March. "When you sign a new four-year deal at the age of 28 or 29, you do it with a specific purpose in mind," the Germany international told bundesliga.com. "It's about trying to get the team and the club back to the level we were at before. That's where we all want to be again."
"I was delighted to hear he'll be our coach," said Reus, who had his best-ever Bundesliga season under Favre at Gladbach in 2011/12, scoring 18 goals and providing 11 assists. "Hopefully he'll be here for the next few years, because obviously I know him from our time at Gladbach. He prepares very meticulously for every match, whether it's the Bundesliga, Champions League or the DFB Cup. You can be sure he'll work on the smallest details.

"He wants to win every game," he continued. "Hopefully we can live up to his expectations and he can be satisfied with our performance level, but obviously it's not something that'll happen over night. We want to have the ball and have the opposition chasing after it. Last season didn't go to plan in terms of either the football or the results, especially before the turn of the year. Now it's about setting new targets."
Among those - after progressing to the DFB Cup second round last week – is to challenge Bayern Munich for the Bundesliga crown this term. BVB got off to a dream start in that respect, hitting back from a goal down to beat RB Leipzig 4-1 on Matchday 1 of the new campaign. Captain fantastic Reus registered a goal - his 100th in the Bundesliga no less - and an assist. Talk about leading by example.
