30 million euro, while a "little" painful, is actually not that much for a player like Jovetic. To whomever complains about that price tag and talks about guarantees, the only type of players that spring to mind that bring you those types of guarantees is Suarez, Aguero, Tevez or last season RVP. Now how much would a club have to pay for Suarez? Minimum 40 million I'd say. Man City would not let go of Aguero for less than 40-45 as well either, and that's assuming he'd like to leave.
Who else is on the market? Cavani? He'd be what? 35 - 40 million to get. Falcao? Minimum 40, more than that most likely. The market has changed, that's the reality of the situation, and at 30 million Euro, I think Jovetic is the best player available at the moment, unless you want to cheap out and get Sanchez who has flopped spectacularly at Barcelona and just doesn't have the same amount of talent as Jovetic does.
