Or Cavani, or Falcao. If it turns out that the rumored Chelsea offer to Jovetic was true, will that suddenly make him a better player than he is?
Ok, then it's the same as choosing Henry for sky high wages instead of paying 25-30m for the 21 year old Messi in 2008, who ended the season with 10 la liga goals. I mean, Henry was a proven quality. And unlike Van Persie didn't have a history record.
And it will be worthy to sign Jovetic. Honestly, have you watched him at least? You seem to be basing your opinion on the "no other big clubs wants him" (which isn't even proven. Milan for example are linked to him and Chelsea were linked to him some 2-3 weeks ago).
The discussion isn't about what Juve needs more or if Van Persie is great. We do need a CF and Van Persie is a huge talent with proven quality. My only complain, a strong one, is about this very expensive choice we are making with a player who, with one exception, was regularly missing 13-20 matches in EPL every season. Even the filled with talent Barca is feeling the consequences when one David Villa isn't playing. For Juve it will be 100 times worse and it will have terrible consequences on our future if Van Persie does what's logical judging from his history, and misses half a season due to injury. It will have a strong influence on our market strategy in the following years.
Go for a CF, but play it smart. RVP is too big of a risk to take for Juve. It's a risk that some other teams can allow, but Juve or any other Italian team can't.
