Popis: Let $\Gamma$ be a countable group and $(X, \Gamma)$ a compact topological dynamical system. We study the question of the existence of an intermediate $C^*$-subalgebra $\mathcal{A}$ $$C^{*}_{r}(\Gamma)<\mathcal{A}Comment: All the changes suggested by the referee have been implemented. There is a change in the title, which aptly describes the paper's contents. The paper has been accepted into the Journal of Functional Analysis
