OK, with all the childish "my view is right and your wrong" going on in this thread, I thought I'd give my two penneth for what it's worth.
This view is purely from my observation of him "from the outside", I don't profess to have any ITK insider track on him. All views are based on what I see of him on the pitch (for City, Bosnia and limited rememberance from Dortmund) and also what we are privaledged to witness via CityTV.)
As a footballer
(Technical Skill wise)
I don't think I will be challenged on my opinion that he is the least technically skilful player of our "Strikers" He isn't a player who is comfortable with the ball at his feet with the willingness to dribble past a defender. but I'm pretty sure it wasn't his silky skills that he was bought for, and nor should he be hung drawn and quartered for neither like he does so many times on BM. 4/10
(Target Man)
With his back to goal and asked to bring others into the game etc etc, due to his lack of technical ability as previously mentioned, it limits him in this role. 5/10
(Goalscorer)
Probably one of the best at converting chances into goals. I don't have any stats at hand, but I think he would be up there at putting away clear chances. His awareness in the box, his acuracy, his lethal poaching abilities puts him as our best goalscorer in respect of numbers. Cross a ball into the danger zone, 100% everyday I would want it to fall to Dzeko to put it away, and I'd say he would have the highest ratio of doing that. Left foot, right foot, header, arse shin etc etc. 1 on 1s with keeper, I'd back Dzeko to slot it home (or at least make the keeper work) nearly all the time. You set your style of play to provide crosses and through balls to a striker, I would say he is one of the worlds best at putting them home. 9/10
(Tracking Back)
Awful. Sheer awful. This is my biggest gripe with the big man. If He/We lose posession, he is so lazy. He spends all his time complaining to the ref rather than getting on with winning the ball back. He needs a rocket up his arse in this area. He needs to take a leaf out of Tevez's book in this part of the game. Now, because this is purely a flaw in attitude, this part of his game can change dramatically very quickly given the right encouragement and mentoring.
1/10
("Team Mate")
Couldn't think of what else to call this. It seems from the footage we see behind the scenes, he gets on with the squad members, wears a smile and works hard in training. He comes across as a likeable guy. Has had tantrums, but are they down to fustrations with himself and or the previous alouf management
All in all, he is here as a striker. Scoring goals is what he does very well given the right provision and supply.
Id be more than happy to keep him and use him in the best way possible
Smack his lazy arse and give him the ball infront of goal and we will outscore every other team in this league
