We report on our computation of the pion transition form
factor ${\cal F}_{P\rightarrow \gamma^*\gamma^*}$ from twisted mass lattice QCD in order to determine the
numerically dominant light pseudoscalar pole contribution in the
hadronic light-by-light scattering contribution to the anomalous
magnetic moment of the muon $a_\mu =(g-2)_\mu$. The pion transition form
factor is computed directly at the physical point. We present first
results for our estimate of the pion-pole contribution with
kinematic setup for the pion at rest.
