Lack if pace is what is worrying me.
It's tough to imagine someone of his height and build to be very mobile (Yes, I know that Dzeko is an inch shorter, but Llorente has nearly 20 lbs on him)
However, from what I have seen, he is mobile enough. With this team, the flow of attack will always come through the midfield.
The will not only create space with the excellent movement of Vidal and Marchisio, but they will also open up angles in and around the box that Llorente, if he has the presence of mind to do so, will attack and be able to create his scoring opportunites.
And if Vucinic and Gio play to their strengths, then Llorente should be receiving an ample amount of clever passes in the box as well
Personally, I would be very happy with this transfer if it were to happen. I think that he is the type of strong, physical, presence who knows how to use his abilites in and around the box that Juve will be looking for
