The football world is always waiting to uncover the next Kylian Mbappe or Erling Braut Haaland.
Clubs can save themselves a fortune by identifying the stars of tomorrow earlier than their rivals.
For the fans, it's a matter of looking ahead to the players who could be dominating in just a few years' time.
With that in mind, UEFA asked their reporters to identify 50 emerging talents who they believe are set for big things in 2020.
There are no shortage of teenagers making a name for themselves across Europe.

Many of these, such as Fati and Greenwood, will come as a surprise to nobody, especially not Barcelona and Manchester United fans.
In fact, Greenwood has done so well United are reportedly going cold on signing a new striker.
Others may be a little obscure now, but we get the feeling they won't be by the end of the year.
Rafael Leão, for example, has been described as a Portuguese Mbappe, with coaches at Sporting Lisbon suggesting he is better than Cristiano Ronaldo was at the same age.
Fiorentina's Dušan Vlahović is also attracting welcome comparisons with Zlatan Ibrahimovic; let's see how the two compare now they're both in Serie A.
The truth behind all of their respective development paths is that these players need opportunities.
Troy Parrott is already playing for the Republic of Ireland senior team but is finding it hard to break into the Tottenham first team - though that could change in light of Harry Kane's injury.
The list might be lengthy, but remember as many of these names as possible. Any of them could be the next big thing.News Now - Sport News
