I agree that we need a poacher more than JoJo but I don't see us getting Cavani, Higuain or Dzeko. That being said if it's between Llorente and JoJo I would pick the latter without thinking twice.
Because even I, a huge Jovetic supporter, do not believe that 30 million is worth it for Juve to spend right now. Trust me, that pains me a lot to say it.
It's too late in the mercato for Fiorentina to change their entire shape of the squad, since it was built with him primarily in mind. It is going to take a lot more than 30 million for Jovetic to be sold, at this point.
