Emre Can from an interview with Kicker this weekend, on his move to BVB:
"I know that Borussia Dortmund had contact with Jürgen Klopp. I am pleased that Jürgen, one of the greatest coaches in the world, must have made a positive judgment about me. After a good two and a half years of working together, he knows me very well.”
Also:
“I had three Premier League deals available, including one from Manchester United. But I didn't think about that for a second because of my Liverpool past.”
