So how does the Mexican Premier League stack up?
What's a general ranking of the various leagues worldwide?
Mexico's top flight league is the best league in N America and the third best league in the Western Hemisphere, though at any time could fluctuate back and forth from 2nd to 3rd depending the strength of either Brazil or Argentina's currency. Generally it's 1. Argentina, 2. Brazil, 3. Mexico, 4. MLS. The best teams in MLS with a lot of depth and good coaching (LA, Seattle, Salt Lake) would be competitive if not downright good in any of those leagues. MLS's problem on the whole is depth. It's getting there though, as our youth development catches up to those other leagues.
Historically the best leagues in the world are EPL, La Liga (Spain), Serie A (Italy), Bundesliga (Germany) with Ligue 1 (France), the Eredivisie (Netherlands) in the mix. Scotland had a great run near the top in the 60's and the early 90's, Holland did in the 70's and 90's, Portugal in the 50's & 60's but the constants are the big 4 of England, Spain, Italy and Germany in that order. It has a lot to do with each country's respective economies.
Right now, off the top of my head, I'd rank them like this:
1. Spain - Not as deep as England but the strength at the top can't be beaten.
Behind them you'd have in some order the Russian league, the Netherlands, Argentina, Brazil, Portugal, Mexico, MLS, Belgium, Scotland and the second divisions of the big leagues like the English Championship, Serie B, Bundesliga 2 etc.
After the big leagues, individual clubs are more important because there are big spending clubs in all leagues that can buy more talent than their counterparts like the Galaxy, the Red Bulls, Chivas, Club America, Boca Juniors, Corinthians, Red Star, Zenit St Petersburg, Anzhi Machalaka etc.
