Ronaldinho came in 2003, when Barca was weaker than today.
His teammates were Kluivert, Saviola, Lucho, Cocu, 23 years old Xavi etc.
In the 2nd season, we signed Etoo, Deco, Guily, Edmilson, Larsson. That was a good team, but in that season, in September: Motta, Edmilson, Larsson and Gabri suffered knee injuries and Sylvinho was out for the majority of a season. We had only 3 attackers and 3-4 midfielders for the whole season, zero rotation. We won a title, but los to Mou's Chelsea.
In the 3rd season, we won La Liga and a CL without injured Xavi (knee ligaments).
In the first 3 seasons, Messi was a non factor.
He didn't play in the first 2 seasons, and in the 3rd he started to get minutes and turned into a starter but got injured in CL quarters and missed the remaining of a season.
So, Messi was a factor only in the 4th and 5th season, but even then he got injured often.
In the 4th and 5th season, Ronaldinho gained weight, started to get injured often, Messi was injured and Deco was getting divorced and he totally disappeared mentally.
On the other hand, Neymar came in 2013:
Messi was 26
Iniesta was 29
Busi was 25
Alves was 30
Mascherano 29
Alba 24
Fabregas was 26
And in the next season, we signed 27 years old Suarez.
In the 2nd season, Neymar played with Messi, Suarez.
Xavi was still there, Iniesta/Busi/Alves were still very good, Rakitic was young and babysitting for everyone, we had 2 good goalkeepers back then.
It is hard to call Rijkaard's Barca better in terms of names than MSN Barca.
The only difference is that Rijkaard's Barca was maybe more combative and less amigos-based.
For me, the main difference between Ronaldinho and Neymar is that Ronaldinho is looking to score a goal and assist as his purpose of a game.
And while he is direct and trying to score, he is using tricks on top of that.
So, tricks and fun are only secondary in his game to reach the main goal = a win/to score goals.
Yet, with Neymar, it always seemed as TRICKS are primary in his game.
You often get an impression how he is not there to get to the goal as fast as he can, but to showboat, show clown tricks, humiliate opponents, create good Youtube videos and GIFs and similar.
Do you remember that classic Neymar action when he slows down, stops and wait for an opponent to show him tricks and waits to be fouled and then he rolls on the ground?
Or how many times he dribbles past the opponent, ONLY to slow down, allows the opponent to catch him and then he tries to humiliate/dribble him again?
Or that famous bacwards dribbling when he for some reason doesn't want to pass the ball and dribbles towards his goal until he gets fouled?
Imo, something is fundamentally wrong in Neymar's head regarding showboating.
We all know Ronaldinho's videos from Barca and Brasil, but here is a video of pre-Barca Ronaldinho from 2 PSG seasons, aged 21-23.
Look at this video and look at the difference compared to Neymar: Ronaldinho is direct, Ronaldinho is fast, Ronaldinho doesn't fake fouls, Ronaldinho doesn't fall down, Ronaldinho doesn't showboat for no reason, Ronaldinho doesn't dribble backwards.
He just takes the ball and tries to score/make an assist and that's it:
