They've been interested in Chamakh for quite a while and need money, which is why this rumour just became a little more likely. They would get both a striker and some significant money in exchange for Jovetic. And they'd avoid selling their fan favourite to another Italian team.
I think Chamakh would do well in Florence if he could man up and get back to the player he used to be too. They've got one of the best crossers in Europe in Vargas who'd thrive on having someone with proper heading ability up front.
