Gintel: I occasionally contact Klopp, but the time to go to Dortmund was not right.

German defender Gentl, who currently plays for Freiburg, was interviewed and talked about his past experience in playing for Dortmund.

Gentle said: "Klopp brought me to Dortmund, but the timing was a bit inappropriate. It was a whole new experience for me, both in football and in life. It was not easy for me to live alone for the first time. Now I may have to admit that it was not very good at that time. But it had nothing to do with him or myself, and I think it would be a little smoother if it was at another time and in another place."

Under Klopp, Gentle had only a few chances of playing in the 2014/2015 season. But Gentle said that the two sides are no longer unhappy now: "We occasionally meet or contact each other over the years, and everything is normal. At that time, there was no complete resonance at the football level, which is inevitable."
