A product of the Central Córdoba youth setup, Grazzini brings a great deal of foreign club experience to the Fire, having played for Sevilla (Spain; 2003), Virton (Belgium 2003-04), Deportivo Italchaco (2006) and Sestrese (Italy; 2007-08). After short stints at the former two clubs, it was with the Venezuelan and Italian sides that the attacking midfielder made his mark, scoring six goals in 15 matches with Italchaco and 22 in 45 appearances with Sestrese.
Following his time in Italy, Grazzini returned to Argentina in 2008, where he played nine matches for Newell’s Old Boys, based in his hometown of Rosario. He then moved to Allevaneda side Racing Club, scoring five goals in 34 matches from 2009-10.
The attacking midfielder joins the Fire from Club Atlético All Boys where he played in 22 matches and bagged five goals for the suburban Buenos Aires club over the course of the 2010-11 Clausura and Apertura tournaments.
