Ronaldo's close control was on an entirely different level to Kaka's in my opinion. Not a slight on the latter there are maybe a handful players to ever have played the game on par with Ronaldo.
Also just to be clear - I wasnt saying Kakas technique wasn't top class, he was flawless in pretty much every aspect especially his passing was an aspect of his game that wasn't nearly credited enough. Just his close control wasnt up there with the very best probably because he didn't need it and his mentality unlike Ronaldinho wasn't as playful
