We show that the quasiparticle states found in a self-consistent Born approximation for the spin-fermion model which describes CuO_{2} planes agree well with experimental data in insulating Sr_{2}CuO_{2}Cl_{2}. It is found that the antiferromagnetic correlations are reduced in the neighbourhood of a moving oxygen hole and the correlation functions can exhibit similar dipolar distortions as reported in the context of the t-J model.
