Maybe it's hard for some of you to actually understand what you read, so I will explain this one more time.
They have earned 64M from selling cavani, we have earned a similar amount from the champions league last season.
So why can they spend 85M on one marceto and we can spend "only" 23?
And the fact that Tevez is better than Higuain has nothing to do with my point- we could have and should have bought better players, some more good players to be exact, in this marceto.
