  We consider an interpretation of the recent lattice data on the
current-current correlators in the x-space. The data indicate rather striking
difference between (axial)vector and (pseudo)scalar channels which goes beyond
the predictions of the standard non-perturbative models. We argue that if the
difference is to be explained by power corrections, there is a unique choice of
the form of the correction. We discuss the emerging picture of the power
corrections.
