V-shaped neckline
Light yellow puma logo with white frame... sharp contrast with the black shirt.
Being consistent with Puma logo, the number is also light yellow in colour and framed by white rim.
There is no Puma logo on the left sleeve, but 'hidden ITALIA' instead, LIKE! ^ ^
I couldn't find the photo of Flachi, but Gattuso and Miccoli wearing the same shirts in action.
