To be fair I haven’t seen the majority of the leagues but their rating system seems to favour the South American countries maybe because they are mid-season and the European leagues are pre-season.
Off what I have seen of Ecuador’s Serie A 14th place seems quite kind but Mexico’s Premier Division should be higher placed than at 11th. Saudi Arabia and Malaysia are notable inclusions at 15th and 23rd.
Personally I would have the EPL at the top closely followed by La Liga then the Bundesliga. In y opinion the Brazilian and Argentinian leagues are the strongest on their continent but wouldn’t be in my top 5, probably the top 10.
Personal top 10 leagues.
English Premier League
La Liga
Bundesliga
Italian Seria A
French Ligue 1
Brazilian Série A
Argentine Primera División
Portugese Primeira Liga
Mexico’s Liga MX
Chilean Primera División
I have to stress that I have hardly seen any of the leagues in Asia so do not have a full appreciation of their merits. To date I have not been impressed by the MLS.

The iffhs is probably not looking at league standard if not the epl and others would be highly placed
but if we looked at player quality then spain would arguably be the best
Arguably, the best players in the euro’s were epl based..but it is very close between epl and la liga…
with all the goings on in the Italian league it seems difficult to asses it objectively. And how long will it take for the MSL to get into the top 25?
Yeah…Italian and Turkish leagues are questionable right now,as is Spl…can’t see the MLS becoming good overnight despite the faded stars..all the best yanks play in Europe or want to
just IRAN
German!!??
