What? The time period where English teams were the best in Europe, you mean? When there was an English side in a European final from 2005 until 2012? That famous weaker and poorer league? OK, mate.
The PL was strong back then but the clubs weren’t that much stronger than the best teams in Europe… Right now we have 3 English clubs in the top 4 of Uefa’s 5-year ranking. We’ve never seen this before.
The only reason your series doesn’t apply to this period is United missing the EL final in 2020 against Sevilla in a game we deserved to win… When looking closer at that period we find Liverpool failing group stage behind Lyon and Fiorentina, and we see Arsenal getting trashed by Barcelona, or Spurs trashed by Madrid… It’s not that much different from now. The domination is much more obvious now than ever before.
