They will exclusively air the next three seasons starting next year: 2018/19, 2019/20 and 2020/21, but the future editions will have many changes.
In Spain, the Tuesday fixture will no longer be broadcasted freely. An unprecendented occurrence in a country where, not long ago, two matches were shown every week.
However, kick-off times will change the most. No longer will games start at 19:46 GMT.
Two group-stage matches will begin at 19:00 and the remaining six will start at 21:00. The days will stay the same: Tuesday and Wednesday.
