The measurement of the azimuthal anisotropy of neutral pions at high transverse momentum helps unveil the path-length dependence of jet-quenching. A further motivation to study this anisotropy at LHC energies is given by the fact that the azimuthal anisotropy of neutral pions at RHIC is under-predicted by current QCD energy-loss calculations. The neutral pion yield as a function of the emission angle w.r.t. the reaction plane is measured with the ALICE PHOS and EMCAL calorimeters as well as by reconstructing photons via their conversion into $e^+e^-$ pairs. In addition to the azimuthal anisotropy of neutral pions the reaction plane dependence of the nuclear modification factor, $R_{AA}$, is presented.
