Jovetic is good and all but how will it work with two SS upfront and none of them are particularly interested in being in the penalty box and actually scoring the easy goals? We need a threat to the defense off the ball, someone who'll run, stretch the defense and will be ready to head in a cross or just score an easy return from the goalkeeper.
People seem to forget about all of that when we in reality we'll have 3 players like that in Vucinic, Jovetic and Giovinco.
