“After playing for Turbine Potsdam and most recently in England, Caroline Siems joins our team as a young but very experienced full-back,” said Bayer 04 head coach Achim Feifel. “She has enormous potential. And we hope she can provide lots of positive input with her dynamic and attacking style of play.”
Siems, who has played for all Germany junior teams up to the U19s, is looking forward, “to returning to the Bundesliga. Discussions with the Bayer 04 management and the conditions here have convinced me that I can best develop at Leverkusen both on and off the pitch. I’m very excited about the years ahead.”
The defender played for Turbine Potsdam from 2015 to 2020 before moving abroad to Aston Villa last year. Siems made 14 appearances for the Villa Women last term.

The Bayer 04 Women clcoked up a 3-2 win in a friendly against Twente Enschede on Thursday afternoon in the last international break of 2025. In drizzle, Lilla Turanyi (16’), Kristin Kögel (65’) and Paulina Bartz (69’) scored the goals for the Werkself against the Dutch Eredivisie Vrouwen leaders, who are still unbeaten in the league.
