Reus was named club captain by new coach Lucien Favre, a man all too aware of Reus' talent after their time together at Borussia Mönchenladbach, and in his first league game wearing the armband, he inspired his side as only he can to a 4-1 win over RB Leipzig, scoring his 100th Bundesliga goal in the process.
It was a remarkable achievement for Reus, whose very first Bundesliga goal came almost a decade ago. bundesliga.com takes a look back at some of the best and most significant strikes scored by the league's newest entrant to the famed 100 club.
1) Gladbach 2-0 Mainz, 28 August 2009
Reus has of course since found the net a further 99 times in Germany’s top flight, but a strong case can be made that his first goal in the Bundesliga remains his finest. Collecting possession in midfield, Reus embarked on a 50-metre run, slalomed his way into the box and calmly finished past the goalkeeper with the composure of a veteran. It was quite the way to announce himself on the Bundesliga stage.
2) Gladbach 1-1 Bayern Munich, 24 April 2010
This was the first of many Reus has scored against the German record titleholders, for whom he has become a thorn in the side over the years. Against a Bavarian outfit that was top of the table and would win the domestic double that season, the youngster demonstrated his ability to make an impact against the best in the business with a precise finish into the bottom corner.
3) Gladbach 5-1 Cologne, 10 April 2011
A long ball from Dante on to the head of Mike Hanke; a knockdown to Reus, 35 yards out. The youngster takes one touch and fires an unstoppable half-volley into the top corner. Bang!

4) Gladbach 5-0 Werder Bremen, 19 November 2011
In 2011/12, Reus moved to another level as the key attacking weapon in a thrilling Gladbach attack that swatted teams aside with ease on a regular basis on their way to a first ever qualification for the UEFA Champions League play-offs. Against Bremen, Reus got the party started by skipping away from one defender, evading the challenge of another and arrowing a shot into the corner. He went on to score twice more that afternoon and complete his first top-flight hat-trick.
5) Gladbach 3-1 Bayern, 20 January 2012
Gladbach had already beaten Bayern once that season, with Manuel Neuer making the headlines for the wrong reasons in his first season in Munich. Unfortunately for Germany's No.1, he saw himself embarrassed again in the first match of the Rückrunde after a poor kick out of goal left his net unguarded. Reus capitalised and calmly finished from all of 40 yards to open the scoring in a chastening defeat for Jupp Heynckes' side.
6) Dortmund 2-1 Bremen, 24 August 2012
After "coming home" to the club that had released him as a teenager, Reus wasted no time in showing Borussia Dortmund what they had missed out on, seizing onto a loose ball and firing an instinctive finish past the Bremen goalkeeper for the season's first goal.
7) Dortmund 5-0 Gladbach, 29 September 2012
In his first appearance for new club against his old, against whom he has shown little mercy in the years following his departure from Gladbach, Reus showcased his remarkable striking ability with a brilliant curling shot into the top corner. His former team-mate Marc-Andre ter Stegen was left utterly beaten.
8) Augsburg 1-3 Dortmund, 10 November 2012
Reus has scored five times from free-kicks in the league, but this one against Augsburg arguably stands out as his finest from a dead-ball situation. From an almost impossible angle, Reus applied a deadly combination of power, dip and curl to find the net via the inside of the post. What a strike.
9) Freiburg 0-3 Dortmund, 7 February 2015
It seems crazy to think that Borussia were bottom of the table for a spell during a fraught 2014/15 campaign, Jürgen Klopp's final season in charge. Bottom they were heading into Matchday 20's visit to Freiburg, however, where Reus, who had missed a large part of the first half of the season with injury, opened the scoring in a priceless win for beleaguered BVB. Eight more victories in the second half of the season saw them recover to finish seventh and reach the UEFA Europa League.
10) Gladbach 0-1 Dortmund, 18 February 2018
In his second appearance of the season having again been out injured, Reus showed once more his special ability to rediscover his form almost instantly, scoring with another simply wonderful curling shot, reminiscent of the one that sailed over ter Stegen's head all those years before. His return to the team was the catalyst for another strong finish to the season for BVB, with Reus contributing a further six goals in 10 appearances as Borussia finished fourth and qualified for the Champions League.
