Fifa has announced an overhaul of its world ranking system after complaints that it was too complicated.
Changes will be made after this summer's World Cup in Germany
The main change is that a national team's ranking will be based on results from the last four years, not eight.
Goals scored and home advantage will no longer have any bearing on placings and other aspects, including importance and strength of matches, have been revised.
The changes will come into effect after the World Cup ends on Sunday, with the first new rankings revealed on 12 July.
Fifa president Sepp Blatter said: "I am convinced that our experts have come up with a satisfactory solution for a new way of calculating the ranking.
"We have acknowledged the need for a substantial revision. We are aware that it is difficult to meet everybody's expectations but are confident that the new system will provide an accurate measure of the strength of each of our member associations."
