It would be better to go for a support striker to complement Llorente.

People need to get this into their head.
No longer are Juve in a position where they are just flailing around looking for any good attacker to join them.
They now have a very good CF in Llorente to plan things around.
They also already have Vucinic who has been doing well, so a signing should only be made to really improve things.
Juve need to be looking for someone with pace, good movement and an eye for goal.
