Union Berlin has signed Michel Aebischer. The 29-year-old Swiss international player moves from Italian top-flight club Pisa Calcio to Köpenick. Both clubs confirmed the transfer on August 19, 2026. The base transfer fee is reportedly 3.5 million euros and can rise to up to four million euros through bonus payments.
The Situation
Aebischer is a central midfielder and is expected to strengthen the Berlin offense. The club announced the transfer through its own channels. Union did not make a specific statement about the contract duration.
Background: from Young Boys champion to Bundesliga player
Before his time in Italy, Aebischer played for BSC Young Boys, with whom he won several Swiss championship titles. He then played for FC Bologna and won the Coppa Italia in the 2024/25 season, before joining Pisa. For the Swiss national team, he participated in the 2022 and 2026 World Cups and the 2024 European Championship.
Union Berlin is taking another step in the team's planning before the Bundesliga start. The addition brings experience from Serie A and international competition.
What is still open
The exact contract duration has not been officially stated by Union; it remains open. When Aebischer will make his debut for the Berliners, it depends on his training status. The Bundesliga start is scheduled for the weekend from August 28, 2026.
