  The equivalence between the Non-Abelian Nambu model (NANM) and Yang Mills
theory is proved, after demanding the Gauss laws at some initial time to the
first one. Thereby, the Lorentz violation encoded into the constraint that
defines the NANM is physically unobservable. As result, the Goldstone bosons in
the NANM arising from the spontaneous symmetry breaking can be identified as
the standard gauge fields.
