Can somebody please explain why people are unhappy about this to me? As it makes no sense to me.
If you are a fan of one of these clubs this is good for you as your team will be playing an extra midweek match, you get to watch your team play more football, against better opponents than normal, and if you're a season ticket holder you get more football for your money.
If you're not a fan of one of these clubs than what do you care /shrug.
Of course things change a bit for their fans if the FA do decide to ban them, but then that majorly benefits people who aren't fans of these clubs as it fixes the issue English football has had for 20-30 years where the richest clubs buy all the top players and win all the things thus remaining the richest clubs.
