From the 2021/22 season onwards, the Champions League will only be available on IPTV. No satellite, no cable, no Sky. DAZN or Amazon stream.
This is not confirmed yet. Just because DAZN and Amazon have the rights doesn't necessarily mean it will only be available online. We're not there yet.
It is very likely that a "normal" broadcaster will buy the rights for certain games/packages from DAZN/Amazon.
With us, Telekom messed up the connection for 4 months and caused one fault after another. We were so glad to have SAT. Our neighbor with IPTV was clearly much less relaxed towards Telekom.
