Many observed globular clusters (GCs) seem to show a central overabundance of mass whose nature has not yet fully understood. Indeed, it is not clear whether it is due to a central intermediate mass black hole (IMBH) or to a massive stellar system (MSS) composed of mass segregated stars. In this contribution we present a semi-analytic approach to the problem complemented by 12 N-body simulations in which we followed the formation of MSSs in GCs with masses up to 3× 105 \Ms. Some implications for the formation of IMBHs and gravitational waves emission are discussed in perspective of a future work.
