I don't want to turn this into a team or league bashing but comparing these leagues is like comparing college football conferences.
Sure .. it's like saying that a team with the funding levels of FAU won the national championship against teams with the funding levels of Notre Dame.
It's easy to play for the title if you're in a big 5 conference, FC Porto is in a small league with lower revenue. But they won the champions league twice while Totenham Hotspur have won jack shit. So you tell me which has more success. The team that wins it all with low funding or the team that can't win anything with tons of cash.
