I don´t really believe Llorente will be a flop, as i told before is a good striker but i don´t know how he will fit to Calcio´s style, more physical than La Liga the point is if he can fill the expectations of Conte and of all of juventus crowd.
I think the increased physicality and lack of space are why players from La Liga often struggle in Serie A.
However, Llorente's size and strength gives him an excellent chance of being able to adapt and do well.
And the expectations of Llorente won't necessarily be that big.
Juve are couple off several years where they haven't had a great striker, so the expectations have dropped a fair bit from would would have been expected if he'd been signed when Trezeguet left Juve.
It also looks like Juve may well sign another high-profile forward this summer, so there shouldn't be too much of a burden on Llorente to carry Juve's attack by himself.

anything under 15 goals would be a failure for 4,5m per season striker, no matter what excuses you make. he gets payed more that almost every other striker in the league (same as Cavani, Milito, less than Balotelli), 10 goal season would be a serious flop return.
Depends.
If Juve don't sign another forward and Llorente is playing with Vucinic, he will be there primarily as a finisher and so he would need to get up closer to 20 goals in all competitions for it to be considered a good season. .
If he was paired with Higuain, Llorente would have more of a target man, link-up type role, with Higuain as the finisher, so 10 goals might be a good return from Llorente in that situation.
If Llorente is paired with Jovetic, Llorente's role would be somewhere in between and you'd look for his goal return to be in-keeping with that.
