UEFA's new Nations League competition will start from 2018 with successful sides from the tournament involving national teams able to earn places at the Euro 2020 finals, the ­congress of ­European soccer's governing body agreed Thursday in Astana, the capital city of Kazakhstan.

Although the exact format has yet to be finalized, four slots for the 2020 European Championship will be made available from the new competition for sides that may have not advanced through the usual qualifying route.

"Twenty teams will advance from the qualifying competition to the Euro 2020 finals - which are being played in 13 cities around Europe," UEFA ­Secretary-General Gianni Infantino told delegates from all 54 member nations at the congress in Kazakhstan, where the new event was unanimously approved.

"That leaves four extra slots to be filled and they will come from four teams from the Nations League who have not otherwise qualified through the qualifiers."

The Nations League will largely replace friendly internationals, which have become increasingly unpopular for many middle- and lower-ranked teams around the continent.

One feature of the new competition will be a promotion and relegation ­element with a four-team finals being held in odd years in one selected country.

Wolfgang Niersbach of Germany, chairman of the National Teams Competition Committee said, "This is a big step for national teams in Europe and we hope that fans will support the new format."

UEFA has spent three years studying proposals for the new competition and while some fine-tuning remains, the concept is more or less agreed.

The continent's 54 teams will be ­divided into four large groups based on coefficient rankings with countries ­competing to become either ­Nations League champions, earn promotion to a higher tier or avoid relegation to the level below.

Ahead of the Euro 2020 tournament, each of the larger groups will be divided into four pools of three or four sides with each team playing four or six fixtures ­between September and November 2018.

A final-four competition involving the pool winners of Group A, the top-ranked section, will start in 2019, whereas playoffs for the Euro 2020 finals will take place the following March.

English FA Secretary-General Alex Horne, who is also a National Teams Competition Committee member, ­welcomed the new competition and told Reuters that "it's a very interesting ­concept."

"Following the expansion of the ­Euros from 16 to 24 teams, the qualifying competition is not quite as intense as it might have been and this new competition should add some spice to the fixture list," Horne said.
