This seems to be the new Juventus 09/10 away football shirt made by Nike which will be available through the FSC shop soon.
The Juventus 09/10 away shirt is grey with black and white stripes coming down diagonally. Embroidered team badge and logo with screened on sponsor in front. Nike Fit Dry fabric that wicks the sweat away to keep you dry and comfortable.
Italy flag stitched on the lower right side of the shirt and smaller Italy flag inside the neck with `J` initial on it.
