In the context of Lorentz-invariant massive gravity we show that classicalsolutions around heavy sources are plagued by ghost instabilities. The ghostshows up in the effective field theory at huge distances from the source, muchbigger than the Vainshtein radius. Its presence is independent of the choice ofthe non-linear terms added to the Fierz-Pauli Lagrangian. At the Vainshteinradius the mass of the ghost is of order of the inverse radius, so that thetheory cannot be trusted inside this region, not even at the classical level.Comment: 16 page
