Simple answer?
No, we aren't ruining the PL. Pep is doing what he does in every league and that's raising the level/standard of that league.
By the way...
2011-2020: 5 diff teams won the league (City, Chelsea, United, Liverpool and Leicester)
2001-2010: 3 diff teams won the league (United [5x], Chelsea and Arsenal)
1991-2000: 4 teams won the league (United [7x], Arsenal, Blackburn and Leeds)
Was the league not destroyed from 1990-2010 when United was dominating the league?
We are brilliant. We don't have to apologize to anyone for being brilliant. The rest of the fans especially fans of "big teams" should ask their owners why they aren't as good, why their singings aren't as good, why they aren't investing back in the team as well as us, so on and so forth.
