In January 2003, 29-year-old Marazzina was loaned to A.S. Roma to replace Gabriel Batistuta, who had left for Inter. In July 2003, he joined U.C. Sampdoria, newly promoted to Serie A, also on loan. He failed to be a regular starter, and in January 2004 moved to Modena F.C. on loan until the end of the 2003–04 Serie A season. He scored three goals during his four-month spell, but could not help prevent the Emilia-Romagna side from being relegated.
