I don't know who's the greatest Italian player ever, but i know that Turk's post in page 1 is the greatest post ever.
I'll +rep it if i didn't already do it back then when he posted it :D
My grandfather would say Giuseppe Meazza, my father will tell you Luigi Riva, i say Roberto Baggio and my son will say Sebastian Giovinco.
Now you see how pointless this thread is :D
