I don't like the top 6 being a closed shop but at least there's more competition at the top than most European leagues. The season doesn't start for a month yet we all know that PSG will win Ligue One, that Bayern will win the Bundesliga, that Juventus will win Serie A, that Barca or Real Madrid will win La Liga etc. At least here you can make a case for 4 teams winning the league and about a dozen teams getting relegated, it's a more open competition.
Incidentally do people prefer how things are now, or how it was 10-20 years ago with Manchester United winning everything and the occasional interference by Arsenal or Chelsea? Or even going back to the 80s with Liverpool and Everton sweeping all before them?
