Eric Garcia (Spain)
The leader of Spain's defence is a player that Pep Guardiola has repeatedly heaped praise upon and recently promoted to his first team.
Garcia came through the ranks of La Masia in Barcelona but moved to England in 2017 and he is now being tipped for a long and successful career at the Etihad.
Nicolo Fagioli (Italy)
"We have a kid, from the 2001 category, and I'll say this: watching him play is a pleasure," gushed former former Juventus boss Massimiliano Allegri.
The "kid" in question is Nicolo Fagioli, who is regarded as one of the Bianconeri's most exciting prospects in years.
Juventus Primavera's No.10 wears the same number for the Azzurri and excels not just as a playmaker but also playing in midfield or on the wing.
Benoit Badiashile (France)
The Monaco colossus was ranked 22nd in the 2019 NxGn list and is a pillar of the French team coached by Lionel Rouxel.
Badiashile made 19 appearances for the Monaco first team in 2018-19 and his physique and anticipation make him a real talent in defence.
Goncalo Cardoso (Portugal)
The Boavista centre-back is being followed by a host of top Italian clubs, including Parma and Lazio, after a fine season in the middle of defence for his current employers.
Portugal have been strong in youth competition in recent years and if they are to make a splash at the Euros much will depend on Cardoso's talents at the back.
However, he is also a threat in the other penalty area, scoring twice during the Toulon Tournament earlier this summer.
Sergio Gomez (Spain)
Another former Barca trainee, Gomez moved to Germany in 2018 when Borussia Dortmund activated his €3m (£2.7m/$3.4m) release clause.
His exquisite ability in midfield has earned comparisons with none other than Andres Iniesta, although first-team opportunities at Signal Iduna Park have so far been scarce.
Hans Nicolussi Caviglia (Italy)
Like Fagioli, Caviglia is another former protege of Max Allegri's and made three first-team appearances during Juventus' Scudetto run in 2018-19.
The central midfielder has also carved out a place with Italy's Under-19s and is blessed with great intelligence and technique.
Maxence Caqueret (France)
Having just signed a new contract with Lyon until 2023, Caqueret could be one of the surprises for the French club in 2019-20.
France's No. 10 is a cultured midfielder who goes to Armenia with a burgeoning reputation, and is quickly making a name for himself with his laser-guided passing out of the middle of the pitch.
Felix Correia (Portugal)
Dubbed the 'New Nani', Correia's talents have attracted attention from none other than Manchester City, who are closing on a €3.5 million (£3.1m/$3.9m) transfer for the Sporting prodigy.
A huge threat on the right wing, the 18-year-old star excels with the ball at his feet, with his dribbling and technical ability a match for most defenders.
Abel Ruiz (Spain)
Ruiz took the 27th spot in the 2019 NxGn rankings and is one of the prime candidates to take the Golden Boot in Armenia.
The Barcelona youngster was called up to the Catalans' first team for the final game of La Liga in 2018-19 and is pivotal to Spain, as their centre-forward, captain and brightest talent.
Eddie Salcedo (Italy)
The Inter youngster is already proving he knows where the net is, scoring 12 goals in 25 games in the Primavera Championship.
Born in Genoa to Colombian parents, Salcedo debuted for Genoa at the tender age of 15 and moved to San Siro last summer. Still just 17, he is expected to be one of Italy's prime goalscoring threats at the Euros.
Colin Rosler (Norway)
The son of former Manchester City favourite Uwe Rosler, Colin has chosen to represent Norway (his mother's country of birth) despite being born in Berlin and representing England at Under-16 level.
He has been on City's books since the age of 11, but unlike his striker father, Colin excels in the middle of defence, where his strength and reading of the game make him a daunting prospect for opposition forwards.
Ferran Torres (Spain)
The term 'potential' perhaps undersells Valencia's gem: he has already arrived in a big way.
The 19-year-old winger made no less than 37 senior appearances for Los Che in 2018-19, and earned 12th place in NxGn while leading Spain to glory in 2017's U17 Euros.
