Born in Vittorio Veneto, Fornasier joined Fiorentina in 2007, but moved to England two years later, signing with Manchester United. Shortly after, Fiorentina filed a formal complaint to FIFA about the transfer. However, no action was taken by FIFA after Fiorentina failed to supply evidences for the case.
When playing for United Fornasier lifted up the 2010–11 FA Youth Cup and appeared with the Under-21 squad; he also appeared in the Dallas Cup twice (2012 and 2013) He left the club in June 2013 after making no first-team appearances.
