That's bollocks. Ronnie had one(if not the best) of the best readings of the game in his prime. The difference between him and Messi, Figo, Laudrup, Zidane or whoever else is on that list is that he did it so effortless it was unreal. Can't see better passer,dribbler,entertainer in the game in his prime. Ronnie didn't have the pace Messi, fat Ronaldo had/have. He had to rely on trickery and creativity and his bag of tricks was bottomless.
At his best he unlocked English/Italian/Spanish defences. Scored against the best at the time and made a mockery out of defenders and defensive minded players like Terry/Nesta/Gattuso..the list is long.
Vision and decision making was incredible. Saying he had a "shocking" one tells me you have no clue. Pure by the numbers he had 95 goals and 77 assists in his first 4 seasons at Barca. Shocking decision making indeed. He doesn't play the same advanced role like Messi to hit 50 goals a season. In his prime he was the playmaker, goalscorer, main man who made the magic happen.
Let's not forget that in the 06' route to the final Ronaldinho was the star man in Barca team, without Xavi(missing half of the season due to injury) or todays Iniesta. Barca had much weaker team at that time.
To me Ronnie remains the most naturally gifted player I've seen in my life. This includes Zidane, Figo, Ronaldo(fat and slim one), Messi, Giggs, Cantona, etc...That doesn't necessary makes him the best out of the lot(for that I rate fat Ronaldo as #1) but when it comes to flair and creativity I can't think of someone better.
