We are also seeing all sorts of the might of bottom English clubs. For whatever reason though, ManCity win 5-0 against them every week, seemingly. Chelsea, ManU have also been winning 4-0. This is all because of the superior quality of bottom English clubs, but they are tired every week.
This is unlike La Liga and Bundesliga. There, Bayern, Madrid and Barca win big only because the rest of the league is shit. Madrid sometimes draw and win small, but their opponents are still shit. Crystal Palace they are not.
