For fuck sake man, just come out and say it. The facts suggests Aguero will not be an upgrade for PSG. He wouldn't. They are different types of strikers and are both close to the top of the pile.
Aguero is better for us and Cavani is better for them.
@Metalartin need to Argue Aguero is better is just a blue tinted position.
Aguero is great, and there are other great strikers too. Cavani being one of them. Aguero might be better in a vacuum (arguably), but he is clearly not better for PSG. And Cavani has been a better striker this year for PSG than Aguero has been for City.
So no Aguero is not and should not be an option for PSG.
