Several models do compete to reproduce the present-day characteristics of globular clusters (GC) and to explain the origin of the multiple stellar populations these systems are hosting.
In parallel, independent clues on GC early evolution may be derived from observations of young massive clusters (YMC) in the Local Group.
But are these two populations of clusters related? In this talk, we discuss how and if GC and YMC data can be reconciled.
We revisit in particular the impact of massive stars on the early evolution of massive star clusters, as well as the question of early gas expulsion.
We propose several tests to probe whether the YMC we are observing today can be considered as the analogues of GC progenitors.
