“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.

There were celebrations among those in black and red at the RheinEnergieSTADION. On Matchday 9 of the 2026/27 Bundesliga season, the Werkself beat 1. FC Köln 2-0 and registered their sixth successive win in the derby. Aleix Garcia put Bayer 04 in front after just seven minutes with a direct free kick. Leverkusen played with discipline and energy after that and didn't allow some fierce challenges to unsettle them. Patrik Schick made it 2-0 in the 86th minute, and Said El Mala's goal in stoppage time for Köln proved nothing more than consolation. Jonas Hofmann crowned the derby win with his 100th appearance for the club.
