Do you rate any young players?
Mbappe, Frenkie, Haaland. Felix is nice, but way too young to lead AM right now.
Btw, even De Ligt isn't bad.
The problem is a current era.
Remember, in 80s, 90s and early 00s, clubs were allowed to have only 3 foreigners or non-EU players.
And EU was way smaller back then and consisted only of a few western-european countries.
So, all South American, African, Asian and even majority of European players were foreigners back then (today: Modric, Rakitic, Kovacic, Mandzukic, Oblak, Handanovic, Jovic, Milinkovic Savic, Lewandowski, Piatek etc would all be foreigners in that era).
So:
1. Barca, Real and big teams weren't buying Vinicuis, Rodrigo, Malcom and similar players like today because they had only 3 free non-EU spots in a team and those places were reserved for the best players in the world in their prime, like Romario, Stoichkov etc
That meant that players like Vinicius and similar were first signed by Sevilla, Atletico, Porto and smaller tams and after a few good years in Europe, they were signed by Barca, Real and Milan.
But today, all Europeans are today EU players, and majority of Brasilians and South Americans now have a grandmother from Italy/Spain, and no one is a foreigner anymore.
Also, add a fact that due to an internet era, teams are 10-20 times more richer today and every single club can afford 50M youngster from Brasil.
When you sum it all, all big clubs, plus all EPL clubs are buying youngsters like crazy (a huge demand), and then clubs like Barca or Real have only 2 options:
1. buy a youngster aged 18, 19, 20, 21 for 50M who is nowhere near of being ready for Barca, but that way Barca will "keep" that player. But that player needs 2-3-4 more years of development in a smaller team, which he won't get at Barca.
2. or let him go to Borussia, Red Bull, Porto, Ajax and then, if a player will develop well, Barca will have to pay 100-150M for him in 2-3 years
And Dembele, De Ligt, Malcom, Vinicius are products of these things mentioned above.
Vinicius wouldn't be bought by anyone in 90s in this age. He would be playing in Brasil or for a 10th place French team until he would prove himself. Today, guys like him are signed by RM aged 17 and then we have major flops over and over.
So, to some extent, youngsters were always more likely to fail than succeed even in 90s or early 00s, but today, chances for a youngster flopping at Barca is even higher than in 90s due to us being forced to buy raw, green and overhyped players due to facts mentioned above.
In 90s, De Ligt would have played at Ajax till the age of 22-23, and then a big team would have bought him, when he would have been way more ready and he wouldn't have struggled as much as today.
Today, he is bought by big clubs aged 19, and everyone are expecting big things right away.
De Ligt is mentally strong and he will probably survive these problems, but a lot of other youngsters will be mentally (confidence) dead after failing in a big club, probably: Vinicius, Jovic, Dembele, Malcom etc.
A jump from smaller to big clubs is even tougher than before, since the big clubs are bigger/richer/stronger than in 90s.
Ajax was probably at a level 70/100 in 90s, since they were allowed to keep their players (since big teams weren't as rich as today and didn't have money to buy all of their players) and big teams were allowed to have only 3 foreigners.
Dinamo Zagreb was at a level 50/100 in 90s.
Barca was at a level 100/100.
Today, due to more money and big clubs having better players, Barca is probably at a level 140.
While Ajax and Dinamo Zagreb dropped even lower, due to losing all players at an early age to big clubs (Modric, Kovacic, Mandzukic, Corluka, Lovren, Halilovic, Pjaca, Brozovic, Vrsaljko etc).
So, you see, a jump for De Ligt in 90s would have been: from 70 at Ajax to 100 at Barca.
While today it is: from 50 at Ajax to 140 at Barca.
Also, he would have go to Barca aged 23, and today he is forced to leave aged 19.
So:
90s: age 23: a jump from a level 50 or 70 to a level 100.
2019: age 19: a jump from a level 30-50 to a level 140.
And then of course that we have millions of Dembeles, Malcoms, Minas, Todibos, Juniors and similar.
And people are wondering why is almost every single youngster a failure today.
