  This note addresses the homogenization error for linear elliptic equations in
divergence-form with random stationary coefficients. The homogenization error
is measured by comparing the quenched Green's function to the Green's function
belonging to the homogenized coefficients, more precisely, by the (relative)
spatial decay rate of the difference of their second mixed derivatives. The
contribution of this note is purely deterministic: It uses the expanded notion
of corrector, namely the couple of scalar and vector potentials
$(\phi,\sigma)$, and shows that the rate of sublinear growth of $(\phi,\sigma)$
at the points of interest translates one-to-one into the decay rate.
