How accurate is The Guardian's Next Generation?

The Guardian has done an annual article since 2014 with top talents of the Next Generation; generally speaking it is players in their age 17 year relative to the article publication. The more recent lists have included 60 players, 2015 has 50 and 2014 has 40. Here are some links: 

A quick scan down those lists shows that most of the listed players do not amount of much so its not really worth deep diving into the careers of people who never made it to the big time. Instead, I thought I would take a look at the current Transfermarkt top 10 and top 50 players by market value for each year, and see how many hits these lists actually got. 

I’ll analyze the players through 2003 (age 21 in 2024); for the younger cohorts we certainly haven’t seen all the real top players of those classes establish themselves yet. 

I will list all the top 10 players on the Next Generation list and any other top 50 players that made the list. Then I'll add the rest of the top 10 that didn't make the list so you can see a comparison of who was on and who was off. I'll also list some notable names that would have made the list at one point but have come down in value. Finally I will give a verdict on the Next Generation class, with the number of top 50 players on the list out of the total.
