It might be hard to imagine being worth £81 million at the age of 18, but for football’s wonderkids, the figure isn’t out of reach.

A leading research group in Switzerland has put together a list of estimated transfer values for the most expensive footballers in Europe — and we’ve singled out the highest-ranking teenagers.

Football think tank CIES Football Observatory adopts a “scientific approach” to its methodology, taking into consideration six factors when putting a price on the head of Europe’s top players:

1. Player performance: The quality and consistency of their form
2. Player performance in relation to their club: Are they the star player?
3. International status: How established are they for their country?
4. Contract: Players with longer deals are more expensive
5. Age: Younger players command higher fees
6. Position: Goal scorers are more expensive than goalkeepers

Here are the five most valuable teenage footballers in the Premier League, La Liga, Bundesliga, Serie A, and Ligue 1, ranked in ascending order.
