Abstract
We will show that the momentum subtraction scheme (MOM) in the axial gauge does not generally lead to small coefficients in a perturbation series. This is in contrast with what is found if the perturbation series is calculated in a covariant gauge. Only if a specific spacelike axial gauge is chosen the coefficients will become small. They are of the same magnitude as those obtained by application of the MOM scheme in a covariant gauge.
