Despite all the talent and all the potential, the striker has never really lived up to all the expectations following an improvement in each of his first three seasons in Sicily. During the 2009–10 season, Morimoto scored an additional five goals, adding a further two during the 2010–11 league campaign. His performances have often been over-shadowed by the likes of Giuseppe Mascara, Maxi López, Jorge Martínez and Gionatha Spinesi, while the signing of Argentine international Gonzalo Bergessio also limited his chances to feature.
