Siems joined Leverkusen in summer 2021 from English Women’s Super League club Aston Villa, going on to make 40 competitive appearances (three goals). All 12 of Siems’ appearances this season have come in the Bundesliga, with six of them starts. The former Germany youth international previously played at Turbine Potsdam between 2015 and 2020, including three years in the Bundesliga.
“It wasn’t an easy decision for me, but I feel ready for a new step,” said Siems. “I had three great and eventful years full of valuable experiences. Also at the times when things weren’t going well, I was always able to count on the support of the club, the team and the backroom staff.”

Bayer 04 will be preparing young talents for a potential sporting career in an even more systematic way in future. The club is breaking new ground to help develop their academic, social and personal skills as well. With the ‘Haus der Talente' or 'Talent House’, Bayer 04 Leverkusen Fußball GmbH is creating a new centre for the development of young athletes in a central location in Leverkusen. Once completed – expected to be in the summer of 2027 – the project will be run in partnership with TSV Bayer 04 Leverkusen e.V.
