Calzaghe unbeaten since he was 14!

17 years old, lost a debatable decision to a Romanian in the 1990 European Junior Championships, the Michael Smyth defeat came before that in the Welsh ABA final, the Barry Bomber actually won his first 16 pro fights before personnel problems affected his career.
If you see a video of the Smyth fight you will see him on his knees celebrating the victory just after the result was read out, thats how much it meant to beat Calzaghe even in those early days.
