Da Hell how can you actually forget the TARZAN!!Which is why I brought up the fact about opinions I've watched them both play and I consider Iniesta to be a better passer and dribbler. Iniesta has never taken free kicks/corner kicks because he's played with the likes of Ronaldinho (One of the best free kick takers of this century if not ever), Xavi and messi, and now Fabregas but I will concede that Zidane was better in that aspect.
Now about the 2008-2012 thing, the team would not be considered the best ever if not for iniesta not only because of his immense talent but because if it wasn't for his goal there would have been no sextuple, barca would've won at most 3 trophies that year. Messi didn't score it, Xavi didn't score it, Eto'o didnt score it. Zidane's goal from the cl final was brought up but iniesta's goal in the semi final was probably one of the most important goals ever scored in Barcelona's history, it heralded the coming of the greatest team of all time. So no I don't agree that Messi is the main reason, I believe the quartet of Messi,Iniesta,Xavi and Busquets is what made Barcelona the Best team ever, take out anyone of them and it can no longer be stated as such, look how abysmal we look with just Xavi's decline or when Busquets/Messi/Iniesta is having a bad day.
Now we can agree that Zidane is a more consistent goalscorer and better set piece taker but you don't agree on that Iniesta is a better assister, dribbler and passer than him, I've watched zidane play and he simply doesn't match up, even when you go highlight reel for highlight reel iniesta far outstrips him in this aspect.
