Are you aware that Dzeko earns at Wolfsburg around 4.5m a year, right? And as probably the hottest striker on the market currently, with suitors like Real, Man City, Juventus, etc. he will not be modest with his wage demands. Dzeko will demand a contract worth anything between 5-7m, if not more, wherever he goes. And for that same money, Benzema will sign for us 100%, as he's an out-of form striker, who was overpaid in the first place by Real and who can not make the same demands as he did while he was a hot commodity from Lyon.
So I really don't get this logic Benzema's wages will kill us, when in fact Dzeko will earn just as much, if not more than Benz.
Bottom line is the transfer fee here. I doubt anyone here would chose Benz ahead of Dzeko if they cost the same. But Dzeko's value rises with each day and Benzema's has already gone down during the past 1.5 year. If the rumors are true and Benzema is available for around 25m, whereas Dzeko will cost at least 35m, it's not so crazy to prefer Benzema. It actually makes a lot of sense.
