We find explicit paths of collapse of the Skyrmion, the solitons in the simplest chiral model of pions (without the Skyrme term); even when the quantum effects of breathing and rotational modes are taken into account. The paths are represented by a parameter of a family of trial profile functions of the hedgehog ansatz which has the asymptotic falloff 1/{ital r}{sup 2} for {ital r}{r arrow}{infinity}.
