I see your point, but you're giving an unfair comparison. How if over 5 year window you give 1 league title and 4 4th place finishes versus 1 CL and 5 4th place finishes? Or over a 5 year window you give 3 titles vs 3 CL Cups ? Which I think Barca racked up that many CL Cups from 2006 to 2011.
In the perfect world - yes. Just like the teams competing in the CL are the top teams across European leagues, the teams competing in CWC are the top teams across the world. However there's one rule that discredits the entire CWC.
So I don't see how Japan's domestic title winners or Morocco's champions could become the best in the world even if they haven't won a continental cup.
And that's why so many people across Europe and rest of the world get so excited. There's no other competition where Man Utd can meat Bayern or Juventus can play Barca and so on.
- And to those who rank PL ahead of CL - I really don't get you. Yes, you could win CL by "luck". Like Chelsea - defend with all you have and play on the counter, play your set pieces right. But still it takes so much. It's kind of saying that World Cup qualifications are more important than winning the actual World Cup, because qualifying takes consistency over a span of 2 years and you play more games.
CL might be rated below PL by some individuals here, but within the football world (players, coaches, staff, club owners) CL is the most precious trophy.
