Where will Jovetic play if he comes? We'll probably use the 4-3-3 again next year so where will we place Jovetic. The only place I can see him cover in 4-3-3 is Vucinic's current spot and I just don't see him replacing Mirko and putting his NT captain and good friend on the bench.
We'll definitely need a bigger squad with lots of quality, but I just don't see Jovetic of all people to be the one who'll put Vucinic on the bench. I can see much worse players than Jojo benching Mirko, but not Jojo himself.
