I've heard good things about Balzaretti but never actually seen him play. Lippi played Zambrotta at right back in the second half of Italy's game against Scotland and he did reasonably well so I wonder if Capello might be tempted to try Gianluca in that position an start Chiellini at left back. That said, Pessotto can do a job as well. He may not be getting any younger but he always puts in a good honest shift.
