This emission, which extends up to 40 TeV, was interpreted to be originated by a fresh population of cosmic rays injected by a PeVatron at the GC. I will present a different scenario which, taking into account for the Fermi-LAT data for the same region as well as for spectral anomalies which have found both in the CR spectra by Pamela and AMS-02 and in the gamma-ray diffuse emission measured by Fermi-LAT in the inner Galactic plane, allows to explain H.E.S.S. and Fermi-LAT results consistently in terms of the emission originated by the Galactic CR sea. I will also try to motivate such scenario in terms of CR anisotropic diffusion. Finally, I will also mention the possible implications of our results for high-energy neutrino astronomy.
