It is well known that one-dimensional Klein-Gordon lattices withnearest-neighbor interactions can support multibreathers with phase differencesbetween the successive "central" oscillators $\phi_i=0\ \mbox{or}\ \pi$(standard configurations). In this paper we prove that in this kind of systems,the standard configurations are the only possible ones, so phase-shiftbreathers (configurations with $\phi_i\neq0,\, \pi$) cannot be supported. Thisfact also determines the linear stability of the existing multibreathers.
