So SI announcing their UEFA deal promised there will be changes in european cups structures. There are changes from season 24/25 but Swiss system supposed to be in UEFA competitions isn't reflected in FM 23.
So i simulated until season 25/26 and you can see Bayern schedule as of 1 September 2025. We already know all 8 opponents while in real life Bayern should learn each opponent after each match (so winners play vs winners, losers vs losers).
Is it a bug which will be fixed or it's a feature and SI can't implement new european cups structure properly?
