The newly-founded UEFA Nations League starts on Thursday September 6, with 55 European nations competing in four leagues.
All Home Nations games will be shown live on Sky Sports from now until the final in June 2019.
There will be a few blockbuster games to start the tournament, as England take on Spain and World Cup winners France face previous champions Germany.
The 55 teams involved will be split into four leagues (A, B, C and D) based on their UEFA ranking at the end of the 2018 World Cup Qualifiers.
Within those four leagues, teams will be split again into groups, which will be made up of either three or four teams.
Within each league, four teams will be promoted at the end of the cycle, while four teams will be relegated. They will then play at their new level in the next competition, which starts in 2020.
The winners of the four groups in League A will qualify for the Final Four competition.
