And this is why the rest of us get pissed off with the flappers. The reason is not that you have an alternative opinion. The reason is that you form a conviction based on your personal prejudices and then you make predictions based on those prejudices. Your post sounds as though you almost want Bony to fail so you can then say how much better Dzeko was, and by extention, how right you were.
We have absolutely no idea if Bony will score more goals than Dzeko. We don't know if the goals he scores will be as important as the goals that Dzeko scored for us. He may turn out to be a better team player than Dzeko though, and he may indirectly benefit the team more than Dzeko ever did. But he may not. No one knows until at least the end of next season when he has had a chance to prove himself. We're not Bony fans or Dzeko fans, We're City fans. We should have no problem calling shit on Bony, or anyone else for that matter, if they do indeed turn out to be shit. But what we should do is give the guy a chance to show us what he can do and then criticise him if he doesn't deliver.
What we shouldn't do is call him out before the season has begun because we see him as taking the place of a player who we have previously admired but who's time has now come and gone. Indeed we should be hoping that Bony does turn out to be a better player than Dzeko, because that is what is in the best interests of City going forward.
