Joe didn't want to be trained by Team GB trainers and so he didn't go to the Olympics, he wanted his dad to train him because he thought Team GB trainers would try to change his punching technique. So they sent Robin Reid instead because they wouldn't allow Enzo to be Joe's trainer for the Olympics.

The Calzaghe's were pissed, and decided to represent Sardinia instead of Great Britain at a dual meet where Joe met Chris Byrd. Byrd had had 300+ amateur bouts and had never been stopped, Calzaghe was the first to stop him (and it was Byrd's last ever amateur bout). Apparently Joe was losing the fight until catching up with Byrd right at the end and getting the stoppage in the last few seconds!
