  The evolution from an anomalous metallic phase to a Mott insulator within the
two-dimensional Hubbard model is investigated by means of the Cellular
Dynamical Mean-Field Theory. We show that the density-driven Mott
metal-insulator transition is approached in a non-uniform way in different
regions of the momentum space. This gives rise to a breakup of the Fermi
surface and to the formation of hot and cold regions, whose position depends on
the hole or electron like nature of the carriers in the system.
