BT Sport has secured exclusive rights to show UEFA Champions League and UEFA Europa League games in the UK.
The provider will be the only place to view live games, highlights and in-match clips of both competitions until the end of the 2020-21 season.
Games will be available in 4K ultra high definition with Dolby Atmos sound, as well as via the BT Sport App.
BT Sport subscribers will also be able to engage with the action via social media, while both finals will be streamed live on YouTube.
This approach was tried for the first time last year and meant more than 12 million viewers watched BT's live coverage of these games.
Guy Laurent Epstein, Marketing Director at UEFA, commented: "UEFA is delighted to have extended the relationship with BT Sport for a further three seasons, taking our partnership to 2021.
"BT Sport has proved to be an innovative broadcast partner, pushing the boundaries and covering the UEFA Champions League and UEFA Europa League in new ways."
He also stated that UEFA is "excited" about BT's plans to target viewers via social media, as this will "engage a growing fanbase that consumes sport in different ways".
John Petter, Consumer Chief Executive at BT, added that the UEFA Champions League and UEFA Europa League are two of the best football competitions in the world.
"We would like to thank UEFA for choosing us as their exclusive broadcast partner in the UK," he commented.
From 2018-19, England, Spain, Germany and Italy will all be guaranteed a minimum of four participating teams in the UEFA Champions League.
This means there may be more games between top European clubs and live matches kicking off at both 6pm and 8pm throughout the group stage.
"The UEFA Champions League is due to get even stronger and we are delighted that fans will be able to enjoy two live matches a night for the first time," Mr Petter said.
