  In a recent study on monopole production [Eur. Phys. J. C (2018) 78: 966],
Baines et al added the potential of a magnetic dipole to the Wu-Yang potentials
for the Dirac monopole and claimed that this modified Wu-Yang configuration
does not affect the Dirac quantisation condition. In this comment, we argue
that their claim is incorrect by showing that their modified Wu-Yang
configuration leads to an infinite number of quantisation conditions. In their
study, they also incorrectly identified the magnetic field of the monopole with
the magnetic field of the Dirac string and its attached magnetic monopole.
