Both Zebina and Camo have been suffering continuous injuries for the last 3 seasons and to say that they suffer those for simply being old is horrendous. Just take a look at Alex here, he's what 3-4 years older than Camo? Yet in three seasons only had one lengthy set back with injury and it happened to be this season.
I wouldn't say any of them are into the Rosisky level just yet as the guy is a legend when injuries are discussed but they certainly make a good case for Juve being an injury torn team for the last 3 seasons.
