“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.

A disciplined defensive performance in the second leg saw Bayer 04 prevail against Olympiacos in the play-offs of the UEFA Champions League 2025/26. Thanks to the 2-0 away win in the first leg, the goalless draw at home at the BayArena was enough to ensure progress to the next round. The Black and Reds kept their opponents away from their goal for the best part of 90 minutes.
