But Sky only have the rights to show the champions league for next season. After that they switch to BT sports. At present to get BTSport free you need to be a BT broadband subscriber. So this time next season you might want to switch broadband to BT from Sky so that you can watch the champions league for free that way, or at least with the discount as a BT broadband user.
But those clever chaps the Sky have tied you in for two years. So now you'll probably have to pay full price for BTSport to watch the champions league. So you might not bother. Well that's what Sky are hoping anyway.
