The ranking system was most recently revamped after the 2006 World Cup, with the first edition of the new series of rankings issued on July 12, 2006. The most significant change is that the rankings are now based on results over the previous four years instead of the previous eight years. The change is perceived to respond to criticisms that the rankings do not effectively reflect the relative strengths of the national teams.
From today's FIFA world ranking we see alot of changes from positions to positions as point alloted from game their play in the international match, win-3, draw-1 or lose.
Italy after their won the world cups up to second position but now down to fifth spots behind England who never won any international this four years.
Brazil remains number one no dough their are five times world champion but their play less international compare to europe country. Argentina is another country still remains number 3 in the world but not a very good team compare to the time of Diago Maranonia. FRANCE NO 2 taking the place from Italy after the september ranking. Czech is up to 7 place and Spain down to 10th.
