Knaak, who is studying psychology at the University of Cologne, wants to give 100 per cent for Bayer 04 right to the end as she made clear: "I've always felt really at home at Leverkusen and I'm very grateful for my time here where I’ve developed really well in personal and sporting terms thanks to the great confidence shown by the club. I believe a new sporting challenge is the right step for my development and I'm looking forward to it. Until then we will give our all in our aim of staying up."
Head coach Thomas Obliers: "Her transfer is a loss for us both on a human and sporting level. Rebecca Knaak has always given 100 per cent for Bayer 04 and now she wants to take the next step so we wish you much success and, above all health, and fitness."
Linda Peckhaus, head of Women's football: "Rebecca Knaak joined us when she was very young and has come on leaps and bounds in recent years, above all on a personal level. We are proud that Rebecca, at the age of 20, is already one of the most experienced players who bears a lot of responsibility. We'd like to thank her for her commitment over the past four years and wish her every success in the future."
