England are joined by semi-final opponents Holland, Switzerland and hosts Portugal in the Nations League finals.
One of the four countries will become the first to be crowned champions of the new competition, with the final in Porto on June 9.
Here, we take a look at some of the highly-rated young players who could have a say on the destination of the trophy.
JOAO FELIX - PORTUGAL
Felix was undoubtedly one of the breakout stars of 2018/19 as he went from Benfica debutant to one of the most sought-after players in Europe.
The 19-year-old has already been linked with clubs such as Manchester United, Juventus and Barcelona and it is easy to see why.
A Europa League hat-trick against Eintracht Frankfurt saw him become the youngest player in the history of the competition to hit three goals in a game - but that was just the culmination of a fine first season in Lisbon.

Felix would have made his senior Portugal debut in March had he not had to withdraw from the squad through injury.
Captain Cristiano Ronaldo will be the headline-maker in the build-up to the tournament on home soil - but Felix could yet steal the show.
FRENKIE DE JONG - HOLLAND
While Felix has been linked with Barcelona, De Jong has already done enough to earn himself a summer move to the Nou Camp.
A fine dribbler and a creative midfield talent, De Jong has been one of the jewels in a young Ajax side which claimed a first Eredivisie title since 2014 and was seconds away from reaching the Champions League final.

At just 22, De Jong will depart Amsterdam having made 89 first-team appearances and with endorsements from the likes of Marc Overmars and Xavi.
His fellow professionals in Holland also appreciate his ability as he was named Dutch Football Talent of the Year - an award voted for by players in the top two leagues - as well as winning the Eredivisie Player of the Season gong.
England will have to be wary of his talents in their semi-final clash in Guimaraes, where he is likely to collect an eighth cap for the Dutch.
