@Preizeuzie25 You are right Blue Sport mainly shows football, but you can also subscribe to Swisscom MySports, therefore either you call the hotline 0800 800800 or you go to the customer centre MySwisscom then there on "Your Products" then "TV" and then "Adjust Options"
Then under "MySports" you can select the German (DE) or French (FR) version, simply tick the box and then click on "next", it costs 25 Chf/ month, cancellation period 3 months, no minimum contract period.
