Forza is a word commonly used by Italians to describe their football/soccer club meaning force, strength or power (example- Forza Milan). The word Onward is a substitution for the word Forza. The word derives from the Trenton area. This is now a word that any and all teams can use not subject to just Italians.
Onward Manchester United!
