I actually tried to mean the two weakest sides and used Sheffield United and Fulham's names because so far this season, they've looked clueless.
My point was like Norwich last season and Huddersfield before that and Villa a few seasons earlier, in every season there are one or two clubs that are just making up the numbers. They're not adding anything competitively. Making the league smaller by removing two worst-performing clubs will ease fixture congestion and benefit all the remaining clubs and make the league even more competitive and enjoyable.
If Sheffield United are good enough, then they'll stay in that 18-club league. If you're not, then you'll go down. It doesn't have to happen overnight. Relegate 3 clubs, promote 2 for two consecutive seasons. I'm not saying remove two clubs randomly or two clubs that have lowest gate income or attendance. I'm just saying remove the two worst performing sides. This isn't such a radical idea either. PL went from being a 22-club league to 20-club league in the space of a single season.
There's just too many fixtures to fit the football calendar. If the proposal to scrap the League Cup and make the PL smaller came isolated, I think they'd have been welcomed. But because they came along with a lot of other financially incentivised proposals and the attempted power grab (which I don't support either), they're going to be thoroughly condemned by most people. Even the people that have been ranting about scrapping the League Cup for years won't support this project.
