Jovetic was often quite good, but injured all the time much like when he was at Fiorentina. If we want the Bony that Swansea had them maybe we should play like Swansea but, ultimately, I don't think anyone really wants that. Negrado was great until he got injured and had a whole host of personal problems which forced in back to Spain. Dzeko only scored 20 goals in one season for City - 2013-14 when Pellegrini took over.
Blaming Pellegrini for Dzeko being a lazy, egotistical, mard arse makes no sense at all. Pellegrini may have many faults but making strikers perform poorly is not one of them.
Dzeko's good in a great team in which all 10 of his teammates are playing brilliantly and laying on a plate 6 yard tap ins for him. Put him in a side playing averagely and he's the first to down tools.
