All this Suarez vs Aguero stuff is a bit silly in my view. The fact is they are both incredible talents that would walk into any team. Trying to suggest one is better than the other is a bit pointless I think. Unless you can rewind history and compare each player in the same team with the same injuries, or lack of, then who knows.
I would say Aguero has the better temperament, but he's not immune from the odd lashing out or stamp as we have seen occasionally. And Dracula seems to be behaving himself a bit more these days. I would add a cheap shot about Dracula's incessant diving, but after the recent performance of one Yaya Toure (not to mention the last 5 years of Micah "Tom Daly" Richards), it would be a tad hypocritical.
Both Suarez and Aguero are incredible players, end of.
