I often point to Dzeko to show what Bony brings to the team. Sure Dzeko scored goals, but how often would you see him successfully take a good touch, or hold off a defender & hold the ball up to lay it off to someone? Dzeko was a goal scorer but had no touch & no passing ability leading to so many lost balls which in turn lead to counter attacks etc. Not trying to slag Dzeko off, he scored many a big goal for City, just using him as a comparison.
Our midfield can happily just play it into Bony with a big CB on his back, and he happily takes a nice touch, gets the team upfield & keeps possession. It's so nice to watch. Useful in closing matches out too.
People seem to be criticizing him for not scoring, but just take a look at his scoring record, it's obvious the goals will come, add into that his other attributes & he's a fantastic player.
Agree with others that he has been unlucky though, obviously signed at a time when 442 seemed to be how we played, then we have done so well with 4231 he's not had many chances - competing with arguably the best striker in the world. He'll be needed this season though, a lot of matches to play & Aguero likely to get injuries.
