We show that, once mapped in the invariant mass of the di-lepton final state, M({\\ell\\ell}), both observables, \\sigma and A_{FB}, display a statistical error which is presently competitive with that assigned to the existing PDF sets and which will rapidly become smaller than the latter as the luminosity being accumulated at Run-II of the LHC grows.
