The Germany centre-back has rejected overtures from Newcastle United and Chelsea to remain in his homeland with Dortmund.

Sule told BILD: "In the last few days and weeks, there has been a lot of talk about me and speculation about what I want to do and why.

"I already decided a few weeks ago to play for Borussia Dortmund in the future. "From our first contact, I felt that those at the club were very interested in working with me. [They] gave me an impressive impression of the role I can play at [Dortmund].

"I had the feeling that they wanted me as both a person and as a footballer. I was impressed by the way they looked after me, so I quickly knew where I was going to play in the future."Dortmund's sporting director, Michael Zorc told the club's website: "We are pleased that we were able to sign a German national team player in Niklas Sule and retain him for four years.

"Niklas has shown us in discussions that he is very interested in Borussia Dortmund.

"He has a lot of experience, calmness in the build-up game and the necessary physique to take the next step with us from the summer."
