I think need to describe fewest rule of UEFA Champion League season 2024/25 because for the first time UEFA using new format and get extra quota from usually phase round each teams play six matches with three home and three away matches for next season will play eight matches for group phase.
I am not familiar with new Champion League format for season 2024/25 because don't read all format rule but some players have disagree with more matches playing than old format. However new format will adopt for next season and interested with new format have teams will participants for the first time after longer time absent.
Some new teams will appearance are Bologna for Serie A teams participants, Girona as La Liga teams, Ligue 1 team have Brest and Stuttgart as mediocre teams from Bundesliga will participants in Champion League next season.
I think it's been explained before and according to the UEFA rules mechanism for the new format is the team who finish at top 8 on League Phase will be automatically advances to the round of 16 and the teams from 9th to 24th places will be playing at play off stages and from this method indeed we will be watching more matches because every teams have to playing 8 matches total from home and away however i am not really sure new format will be effective or not because teams participating in this competition will have a busier schedule than last season
