Yawn. Look if Aguero were that great, City wouldn't feel the need to spend £80m+ on suarez, especially when FFP is starting. Likewise Real would be after Aguero, they're not. Aguero = better finisher, Suarez = more complete player.
Tosh. Firstly at this stage it is all paper nonsense. Secondly, Suarez is better than Nasri, Navas etc so putting Suarez AND Aguero in the same team could be amazing so why wouldn't they want both. As for Madrid, they may think Aguero wouldn't go due to his AM connections or perhaps they believe Liverpool are more of a selling club than City. All conjecture and certainly a weak basis to prove who is better.
Don't get so bothered by someone else's opinion.
