First off - some of you (Damocles etc., sorry for calling out) are forgetting one thing - player like Edin is difficult to let go because, apart from Kun, he's been City's most consistent attacking player since coming here (not game by game, but just overall production).
Second thing - what happens if Bony flops? And never say never. Negredo was "the second coming" for a while, and don't even get me started on BALLOTELLI...and we've seen how that turned out. Then Jovetic (who now appears to be next odd striker out...
Guess who's common denominator in that lineup of failed strikers. Yes, it is the boy you are so quick to dismiss AGAIN.
Thankfully, I truly believe City management disagrees with the sentiment of giving up a consistent goalscorer to "freshen up" (wtf?) - because such players don't grow on trees.
But, Edin will have to accept 3rd striker role (THIS is the key)...which I really believe he will because he seems to be happy at City, and there is plenty of games to go around.
P.S. to reinforce my point - if management was ready to "freshen up" and if Edin didn't see himself here as a second fiddle to Aguero - doubt they would've signed 5 year agreement this past summer (if I am correct)...so, truly believe he will be here a while.
