You must notice the night and day difference between American TV commentators and the English people?
The Yanks absolutely despise us. Watched a stream of an away game recently and couldn't believe the absolute shite they were coming out with. If they would have done that on British TV they would have caused a riot.
Dzeko is adored by the majority of City fans. He's one of my personal heroes; he helped win us the league which more the majority of my time wasn't even a fantasy I could have had. The problem I have and have always had is that he is unable to be criticised when he deserves it and he is massively overrated. Dzeko is not a world class player. If you pick your squad of 25 world class layers, how many injuries would it take for him to be in there?
I'd actually keep Dzeko if he was happy to not be the focal point of the team and his body language most of the time suggests he isn't. He isn't a difficult player just a highly strung one who is prone to mistakes.
I can put up with anything from City players - punching each other, training ground fights, rape allegations, obviously hungover, obviously just crap, etc. The one thing that I and most other fans will never tolerate is a person who we feel isn't trying their best and this is where Dzeko fits in.
With that said though I have never booed a City player and will never boo one. Isolated shouts in a crowd of nearly 50,000 is going to happen no matter what. But the crowd, or even groups of it larger than a couple of people, have never ever booed Edin Dzeko at any game I have been to nor have I ever heard of it from any person who isn't a big Dzeko fan.
