Hard to say to be honest. But I am very keen to see Llorente play in our systems and under Conte. The important thing is for him to adapt to the culture of the game in Italy. If he does that I think he could score 15 goals in his debut season. If not, I don't think he'll get past 11-12.
If he can be our main target man, then we need a playmaking forward to sub Vucinic when he is in off days (like 2/3 of the season). Gio in that role is proven to be disastrous.
