Naming Balzaretti as a star talent is a bit rose-tinted IMO. Chiellini was one of the, if not THE best player of the Italian under 21 squad for their past two tournaments. Balzaretti is clearly a very nice guy, but apart from pace and technique he's really an average player. Luckily for him left backs are insanely hard to find these days, so he'll probably end up in a good team anyway.
