I think if you search about Cavani before Man Utd signed him that many were against us moving for him.
He's old, got injury problems, will want to be starter, too high wages, ego problems at PSG, etc.
Turns out it worked out well for Man UTD.
Maybe this can work out well for us too.
I would rather have an injury-prone Cavani than an injury-prone Aguero.
Cavani would offer us something totally different. Aguero would offer us the same crap we've had for the past 3 or 4 years. Not to mention, Messi and Aguero have never worked well together for Argentina.
