They have been discussing this for a few seasons.
This version sounds bad because it's 10 group games, rather than 6. This means that by the time you get 6 games in, you could have a load of teams with 4 more games to play and nothing really to play for because they know they can't change their overall position. Teams will start to play their kids or B teams in those games, which they may need to do as its 4 extra games and unless the Premier league reduces by 2 teams or the champions league teams drop out of something, like the league Cup, the players will be even more tired than they are now.
