A Season With Verona is really good, pretty quick to get through even though it's a decent length. The writing does date itself a bit, especially when he starts talking about "blacks." Cool to read about some players with Verona at the time, Gilardino was just starting his career, Mutu was there, as was Oddo. Definitely a good read.
Never read The Miracle of Castel di Sangro, but here's a great article about by the author's son http://www.newyorker.com/books/page-turner/lessons-from-my-father Depressing, but good, and some insight into his reasons behind writing the book.
