Aguero no doubt. He's scored goals in the Spanish League, he's scored goals at International level and he's scored goals in the first season in the premiership. His movement is better than Tevez, he moves the ball quicker, he brings players into play a lot better. Tevez is a class player, no doubt but Aguero works better for the likes of Silva because his movement is fantastic and that's one of the many reasons why he's got loads of assists this season.
For me Aguero is more of a natural footballer than Tevez, I mean that in terms of the way he moves with the ball at his feet.
