  In this contribution I show that by combining imaging and integral-field
spectroscopy it is possible to unravel the internal structure of galaxies. In
particular, I will present the photometric and kinematic evidence for discs
linking them with stellar angular momentum content of early-type galaxies.
Furthermore, I show that the existence of both fast rotators with core and slow
rotators with core-less nuclear light profiles challenges the standard
formation scenarios for fast and slow rotators and suggests new pathways of
mass assembly.
