BVB sporting director Sebastian Kehl added: "Carney is an extremely talented box-to-box player who caused a sensation in the Premier League at a young age. His dynamism, his drive to the goal and his assertiveness coupled with great footballing class make him an exciting player who has not for nothing been through all of England's youth national teams since the U17s. This development has recently stalled somewhat in London. Despite the lack of rhythm, we see a great opportunity in this constellation and hope that Carney will find his old strength again with us."
