Lionel Messi. Diego Maradona. Paul Pogba. Erling Haaland. All superstars of the game, and all players who won either the Golden Ball or the Golden Boot (or in Messi's case, both) at the Under-20 World Cup before going on to become household names.
The 2023 edition of the biggest global tournament outside of the senior World Cup will kick-off on Saturday in Argentina, with 24 teams vying for a title and the chance to say they lifted the one of the most prestigious trophies in the game for their country.
The build-up has been plagued by controversy. Argentina were only confirmed as hosts in March, after original choice Indonesia were stripped of the rights because of the potential for protests during the tournament.
A number of rows, meanwhile, have broken out between clubs and countries regarding whether certain players could be selected. With the tournament getting under way while the European season still has key fixtures to play out, some coaches are going to be without star names who they hoped would be able to lead them to glory in South America.
Manchester United and Argentina winger Alejandro Garnacho is perhaps the most high-profile absentee, while Chelsea and England midfielder Carney Chukwuemeka is one of a number of players who will only join up with their national sides once the domestic campaign is complete.
Despite all that, a number of potential superstars will be on show, and GOAL has joined forces with NXGN to run through 20 players you won't want to miss:
