Barzagli has been the best defender in Europe if not the world in the last couple of years. I think he's worth that cash back then and now.
Him and Chiello for different reasons. Chiello is like our Gentile (albeit a far less brutal and primitive version); a resolute man-marker, indomitable, uncompromising, tough, anticipates and promptly interdicts opposition attacks, he's great in the tackle and second to none in do-or-die defending and shot-blocking. In comparison, Barzagli is like our Scirea; unyielding and dominant, yet clean, graceful, excellent in positioning, and possesses masterful defensive intellect and tactical awareness.
Best two defenders in the world presently. The fact that Juve's defensive unit as a collective, is greater than the sum of it's parts, speaks volumes not about not only their brilliant individual qualities; but that, along with Bonucci, these stand-out qualities compliment each other so well, which in-turn only serves to emphasise Juve's defensive prowess. Hopefully next season Cáceres can remain fit and uninjured, so that he can take some of the load off Licht, Barzagli and Chiello, so that we don't have injury and fatigue issues that plagued us like this year. Both Barzagli and Chiello's fitness and physiological well-being needs to be preserved so that they can serve us well into the future!
