The representation of the parafermionic operator product expansion (OPE) in terms of free scalar fields with the Goddard-Kent-Olive (GKO) stress tensor is proposed. It suggests natural Dotsenko-Fateev expressions for conformal blocks of genus 0. Related asymmetric coset models G × G/G are also discussed. Finally, some remarks on multiloop calculations are presented.
