FIFA are considering replacing international friendlies with a new 'World League', Estadao have reported. This implementation would last a whole year and divide nations into first, second and third divisions.

The proposal comes with FIFA conducting a broad review of international tournaments ahead of next summer's World Cup.

Friendlies have proved increasingly unpopular given the focus on club football and there is a growing perception that they are nothing more than a distraction.

The 'World League' appears to have similarities to the 'UEFA Nations League', which is how European countries will qualify for the 2020 European Championship.

That has led to complaints from South American nations such as Argentina and Brazil who are finding it harder to play lucrative games against European opposition. FIFA are now discussing the idea of the 'World League', which would likely be introduced in 2019 and involve sides from different continents.

The divisions would represent the quality of the countries involved using the world rankings as a criteria, and would be played over the duration of a year.

It might not be the only overhaul planned by football's world governing body. FIFA president Gianni Infantino has revealed that all competitions in men's and women's international football will be evaluated to make them more attractive to a wider audience, and that the review will be completed by March of next year.

How will the world league and club league go hand in hand. Remember same players that play friendly matches are the same with the ones in clubs. Will there be a break in clubs to enable them participate in their respective countries as it is done during friendly matches . I just wondering the possibilities considering the fact the league take longer time to be completed. or will they use different players .
