AC Milan are understood to be keen to swap Antonio Cassano for Roma striker Marco Borriello.
The Rossoneri are thought to be in the market for a striker following the recent sale of Zlatan Ibrahimovic to Paris Saint-Germain.
A move back to the San Siro could now be on the cards for Borriello, according to La Gazzetta dello Sport.
The 30-year-old spent two seasons in Milan before making his loan deal to Roma permanent last year.
