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.

“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.”
