Not if you don't have a true striker in your squad.
I think the discussion here is too simplified to the point of: We need a CF more than Jovetic.
While we undoubtedly need a top quality CF more than Jovetic, the real question is: "Do we need someone more than Jovetic, only because the
someone is a CF"
I think that our squad, as it is now, is more than capable to win serie A again. In CL, after years of absence and/or awful results, I just don't see us challenging and the lack of a CF might only result with being eliminated a round earlier. If there isn't a top quality CF on the market, then imo it's crazy to sacrifice buying Jovetic only to buy a CF.
So it all comes down to how do people rate Llorente and Dzeko. I guess some think buying a CF of their quality is worthy of missing out on Jovetic. Some don't.
Personally I'd gamble and keep Matri as a CF. In Juve's position in serie A and CL, I'd rather have Jovetic play for Juve than buy Edin or Llorente. In the long run, for the time when we will be able to compete in CL as equals to the favorites, Jo-Jo will be much more worthy than Llorente or Dzeko.
Cavani or Falcao would make me say the opposite of the above, but it looks like we don't stand a chance there.
