The strongest National League of the World 2004:
England's Premier League the strongest in the world!
England has the strongest league in the world. England's Premier League, already the second strongest in the world in 2004, has continuously gained in strength, and proven this outside of the British isles as well. The renaissance of Italy's Serie A continues, and the Première Division of France – by now the third best league in the world – is also gathering strength. The instability of Spain's top clubs at the national level and their poor showing at the European club championships for over a year now have caused Spain's Primera División to crash from first place to fourth.
While Germany's Bundesliga has risen by one place (now fifth), the Eredivisie has made great strides, propelling the Netherlands to seventh place, right between Brazil and Argentina. Equally spectacular gains were registered by the Russian and the Ukrainian leagues, which are now being funded a great deal better and so made the "top ten". The Primera División of Mexico is currently not only the strongest league of the CONCACAF region, but also the third strongest in Latin America.
Other national leagues which made great improvement in 2005 include those of Romania, Switzerland, Bulgaria, Denmark, Ghana, Morocco, Egypt, Norway, Slovakia, Estonia, Poland and especially the United Arab Emirates, now the strongest Asian league, before Saudi Arabia and China. On the other hand, the East Asian top leagues – Japan and South Korea – are going downhill. A similar downturn has been observed in the nation al leagues of Peru, South Africa, Latvia, Hungary, Israel, Senegal, Sweden and Croatia.

The classification of the best leagues of the world is made objectively without any outside influence of any sort. We follow the criteria that the level of performance of a league is reflected by the best classified teams of that league who in turn usually represent their country in international club competitions. If one looks at the football power-houses of the world, one notices that regularly 4 or 5 clubs of their leagues are always competing in continental competitions. By adding the points won in all competitions by the five best placed clubs of each league, we have the points for the country which in turn helps to establish a fair classification. It is important to note that only the yearly classification is representative, since all competitions move along the whole season and over twelve months, we have an objective view of the best. This system has been used since 1991, and it is recognized today as the most precise in rating the leagues of the world.
