Yes this is true! Many young European players have a great possibility of playing in some European team, of course, there are teams that are the elite of Europe, but there are also teams that are of a lower quality.
For a young man to play for a big club, it will depend on his performance, opportunity and also on his manager.
In the last world cups, I confess that Germany played below its potential, it is far from being the team of the 2014 cup, I could even say that the German team is in decline, another team (outside Europe) that is also in decline is Brazil, they will hardly have another team like the 2002 or 2006, for example.
I am not sure whether you can compare Germany with Brazil. The problem with Germany is that younger players are not coming up. They are overdependent on some of the oldies such as İlkay Gündoğan, Marco Reus, Manuel Neuer and Thomas Müller. On the other hand, although there is some dependence on Neymar, Brazil do have a great bunch of younger players. I am talking about Antony, Emerson, Vitor Roque and Raphinha. The only issue with Brazil is that their national league is not strong and most of the players are dependent on European leagues.
I didn't know of the football situation in Germany, I imagined that they had some young promises to compete in the next world cups, but I believe it will be difficult for us to see a Germany like 2014 world cup.
Regarding Brazil, unfortunately they don't have a new star to replace Neymar, they have good players and that's true (Raphinha, Vini Jr, Casemiro, Richarlison and others).
The Brazilian national league (Brasileirão/Copa do Brasil), it is weak compared to European teams, but there are good teams that always stand out in Libertadores and Sul Americana, Sao Paulo, Palmeiras, Flamengo, Corinthians, which are some examples.
let's be honest, how many times has neymar saved the brazil national team? my answer is simple: in recent times brazil doesn't need neymar, just see that in the last world cup he was injured and there were some games in which he didn't play and even so brazil did very well, as for the brazilian league not be very strong, I disagree, the problem with the main team of Brazil is that they put strange coaches, who do not perform well before they become coaches of Brazil and when they become coaches of Brazil these same coaches call the same players to play in the core team
It's not normal that coach X appears and calls 2 players, then coach Z appears and calls the same 20 players, then another coach y comes and calls the same 20 players, it seems that all coaches have the same opinions, which cannot be possible , so there is another problem here, looking at the players who play in the Brazilian league, it is easy to see that they are good players and that they could be playing in the main team, but they are not because they do not play in Europe, and that is something ridiculous
for example i saw a portuguese coach yesterday criticizing what i'm talking about, he wondered what they were calling neymar since neymar is injured and has stopped playing for a long time, could it be that in brazil there aren't players that are good to the point of having to call neymar who hasn't played for a long time and is injured? honestly and shameful, it looks like playing in europe has become a certificate that even if the player stops playing for 1 year he is still better than the active player in the brazil league, something very wrong to think. and this is not going to change because I see that the problem is in the guys who are managing soccer in Brazil
