Ronaldo at Barca and Inter is as good a striker as there's ever been. He had everything.
Ronaldinho was, alongside Kaka, my favourite player(s) growing up. Made the game exciting and unpredictable. Played with a smile on his face too.
In terms of where he ranks in terms of all time Brazilians, I have no idea. Never seen the likes of Pele, Garrincha, Socrates, Alberto, Zico etc play. Can't imagine there are many better though.
