That is a tough call, but I would still go with Llorente because he seems to fit the mold of the type of striker that Conte is looking for.
A striker who knows his place on the pitch, and will not be required to do as much in the buildup of play.
Tall, and strong as an Ox. Also, from the few matches that I have seen of him on replay, he has a bit more technique to him than most people give him credit for.
He could strike fear into the hearts of Serie A CB's
