Maybe not, but Vucinic is making the step up to this team so has to sacrifice himself to be at this level. Benzema doesn't have to come here and do that work.
Offers Juve another option from midfield, as Vidal and Marchisio aren't particularly interested in shooting from long range.
Gives opponents something else to think about when someone is scoring regularly from long range: do you back off, let him shoot and back your goalkeeper; or do you go out to close him down and risk that opening up space that can be exploited if the players passes instead of shooting?
