The pacey winger, who started his career in the Dortmund youth ranks had his first taste of Bundesliga football with Monchengladbach in the 2009/10 season before catching the eye of his former club Dortmund.
And Reus in an interview with DAZN disclosed it was difficult for him to leave the club that gave him Bundesliga experience, but Klopp’s influence was enough for him to join BVB.
"Oh my god, Jürgen was such an animal.
"If Jürgen sits in front of you with his aura, which he radiates even when speaking, with his stature, it's really quite impressive.
"He brings you under his spell and will not let you go. My heart was racing after we first spoke. He was definitely one of the reasons why I signed for Dortmund.
"Jürgen can develop players and make them better. He has a special way about him.
"On the one hand, I was very happy at Gladbach.
"We had a strong side and I really wanted some continuity. I felt that we could grow as a team and play European football in the seasons ahead, something which Gladbach hadn't managed for years.
"But on the other hand, chances to return to your hometown club don't come along often.
"I wrote down a list of pros and cons, and pretty quickly came to the decision that I wanted to move to BVB. It was a matter of the heart.
"Dortmund's my club. I really want to win the Bundesliga with this club. I want to win the DFB Cup again. I want to be in the Champions League final again.
"I have no regrets about staying. I belong at Borussia Dortmund.”
After seven years at Dortmund, Jurgen Klopp resigned as the head coach of the side at the end of 2014/15 season having replaced Brendan Rodgers at Liverpool as he signed a three-year contract with the Anfield outfit before winning the 2018/19 Champions League title with the club.
