In a growing number of galaxy clusters diffuse extended radio sources have been found. The radio emission implies the presence of cosmic rays and magnetic fields in the intracluster medium (ICM) on megaparsec scales. An important question is how the cosmic rays are accelerated that produce these extended synchrotron emitting sources. It is generally believed that shocks and turbulence play an important role in the acceleration of these cosmic rays. In this talk I will provide an overview of the synergies between radio and X-ray observations of clusters to understand the nature of the non-thermal ICM components.
