Would have to be Edin...
To be honest I'm growing increasingly pissed off with Mario, his mannerisms used to be entertaining now its old, yes he's got talent (in abundance) but his attitude completely overrides this in my opinion. In recent games he's spent more time rolling around on the floor or throwing strops like he always does. His talent and his shot are amazing, not to mention being one of, if not THE, best penalty taker in the world, but he's just a bit boring now and if he truly wanted to be a great player at city, he would have sorted his attitude out a long time ago.
Now Edin....
Such a great player scores important goals just when we need them, i think this year will be a cracker for him. Had an AMAZING game at the beginning of last season at spurs, scored a beaut in the "6-1" (although every player did!) scored at the BERNABEU and won us the game at fulham at the weekend and not to mention the famous header to make it 2-2 on the greatest day ever, to name just a few. He just needs more of a chance to prove how good he really is is (the kind of chances Mario has had loads of).
So there. :)
