What about "Stand Up and Fight" - very appropriate with an Italian manager who likes opera - Toreador's (sp?) Song!
Its also the official song of the Munster Rugby team, played at the start of matches, but its usually the chorus that is just sung by the crowd which is:
Stand up and fight until you hear the bell,
Stand toe to toe, trade blow for blow,
Keep punching 'till you make your punches tell,
Show that crowd what you know!
Until you hear that bell, that final bell,
Stand up and fight like hell!"
Here it is recently sung pre-match at game in Thomond Park.
