neither of higuain and berna has any future at juventus, so i don't see too much of a difference, be it short or mid-term
the same way dybala and cr deserve a better winger than berna, the better winger you mentioned deserves a better 9 than this current version of higuain. even cr7 - dybala - kulusevski looks better than anything with this higuain in the middle. higuain is old, unmotivated and above all, homesick, even more than tevez was before he returned.
