We can't compare Pele, Ronaldinho, Ronaldo, or other similar players with Neymar, they played for their national teams for a long time and they earn many achievements also compared to Neymar these players had much better performance and they had more stability while a player like Neymar can't have weeks of good performance and then just like this year, he can disappoint while the team.
I think the generation of golden players in Brazil is over and that's why they couldn't earn many achievements recently in the world cup.
The truth is that the likes of Brazilian Pele, Ronaldinho and Ronaldo were the best players of their football days infact Pele is still regarded as the greatest player to have ever graced the beautiful game of football.
However I'm of the opinion that they were able to achieve all they achieved with national team of Brazil because of the high quality players in Brazil as of that time. Neymar on his though have high profile teammates but they can't be compared to this golden generations of Brazilian football
