  We discuss chiral symmetry restoration and eigenmode localisation in
finite-temperature QCD by looking at the lattice Dirac operator as a random
Hamiltonian. We argue that the features of QCD relevant to both phenomena are
the presence of order in the Polyakov line configuration, and the correlations
that this induces between spatial links across time slices. This ties the fate
of chiral symmetry and of localisation of the lowest Dirac eigenmodes to the
confining properties of the theory. We then show numerical results obtained in
a QCD-inspired Anderson-like toy model, derived by radically simplifying the
QCD dynamics while keeping the important features mentioned above. The toy
model reproduces all the important qualitative aspects of chiral symmetry
breaking and localisation in QCD, thus supporting the central role played by
the confinement/deconfinement transition in triggering both phenomena.
