I dont think that Amauri would defend any better than Palla, as a winger and i m sure that Palla would have shined much more if he was a regular at a mid table team, like Palermo...
Amauri is definitely a few steps ahead of Palla and thats not only because of his age.
Amauri though has some realistic chances to challenge for starters place than Palla.
On the other hand Palla has a greater tolerance as a luxury sub than Amauri, Amauri would definitely ask to leave if he was treated as Palla this season...
It seems that our priorities have changed for next year, we will soon see what our managers have in mind for the next year,
-maybe a marginalized role for the aging Del Piero
-a proof that bringing in Iaquinta was a mistake and they should save that money to invest in a younger forward this year.
-the end of Palla's carrier with Juve's jersey
-or the change of our formation, to a much more offensive one, like a 4-3-3, in am attempt to solve our creativity problems without the use of an AMF, creating more spaces for more forwards...
Time will tell...
