abstract
We show that the recent paper \cite{kalash}, claiming that the radiative decays \phi\to a_0(980)\gamma and \phi\to f_0(980)\gamma should be of the same order of magnitude regardless of whether the a_0(980) and f_0(980) are compact four-quark states or extended K\bar K molecule states, is misleading.
